Delivers a few pleasant surprises, including a smart story -- a reverse-E.T. riff that plops an American astronaut down in a world of just-like-us-only-green creatures -- and clever characters...
Adam Markovitz - Entertainment Weekly
The agreeable but flagrantly unoriginal Planet 51 belongs to the mix-and-match school of animated moviemaking.
Stephen Holden - New York Times
This has the directionless, recycled feel of a script by committee.
Claudia Puig - USA Today
Planet 51 is cute, but it's no Shrek.
Michael O'Sullivan - Washington Post
Young children and adults with high pain thresholds will enjoy the movie during its brief pause on the way to your On Demand menu.
Ty Burr - Boston Globe
Planet 51 mainly succeeds at reminding you of all the better movies that inspired it.
Brian Miller - Village Voice
This sharp-looking but unimaginative adventure hasn't the wit of similar kiddie flicks.
Joe Neumaier - New York Daily News
The movie as a whole isn't exactly ground-breaking, and some of the humor tanks. But it has enough action, laughs and candy-hued visuals to satisfy the target audience without plunging grown-ups into despair.
Amy Biancolli - Houston Chronicle
Definitely a planet worth a visit.
Nancy Churnin - Dallas Morning News
Rest assured that nothing of significance will disturb said infant, neither feelings nor images nor ideas. No danger here; just a faint, faraway tickle of boredom.
Kathleen Murphy - MSN Movies
Although not bowling me over, Planet 51 is a jolly and good-looking animated feature in glorious 2-D.
Roger Ebert - Chicago Sun-Times
The script lacks wit, and the in-joke references to cinematic sci-fi classics will soar over little kids' heads without pleasing many adults.
Cliff Doerksen - Chicago Reader
An uninspired computer-animated feature that may satisfy undiscriminating pipsqueaks and nearly no one else, Planet 51 is a low-IQ E.T. in reverse...
Gary Thompson - Philadelphia Inquirer
Mediocre, clunky and just so not special.
Tom Long - Detroit News
A high concept gets low execution in Planet 51, a lame-brained toon that even kids will recognize as an insipid goof on sci-fi conventions.
Todd McCarthy - Variety
"Singin' in the Rain" references? John Glenn? Cold War duck-and-cover drills? What time capsule yielded this script?
Kyle Smith - New York Post
Roger Moore - Orlando Sentinel
Christine Champ - Film.com
With nowhere to go except toward that incongruous moral, the story is getting thin on the ground, obliging director Jorge Blanco to pad with the usual plush stuffing -- bland action and busy edits.
Rick Groen - Globe and Mail
A playful throwback to the days when cartoons were mostly aimed at children.
Kirk Honeycutt - Hollywood Reporter
Instead of spinning its spoof of 1950s sci-fi paranoia in new directions, the movie trades in potty humor and tired sendups of The Terminator and Star Wars.
Glenn Whipp - Los Angeles Times
A poorly animated, poorly conceived, utterly predictable science fiction adventure without a single shred of originality.
Todd Gilchrist - SciFi.com
Nick Schager - Time Out
Dean Essner - Dark Horizons
Dave White - Movies.com
"A poorly conceived comedy spotlighting a collection of anal-centric humor that's about as appealing as baseball bat to the face."
Brian Orndorf - BrianOrndorf.com
In terms of animation, Planet 51 is out of this world. Then there's the story and the characters, which are about as dull as a dirty penny.
Philip Martin - Arkansas Democrat-Gazette
A short-sighted assembly of sci-fi references and scatalogical humor that should nonetheless placate undemanding tots ... for ninety minutes or so.
William Goss - Cinematical
Nothing really gels and Planet 51 just comes across as shrill, rushed and unfunny.
James O'Ehley - fantastiqueZINE
While certainly diverting, its overly frantic attempts at humour, pointless homages to other films and lack of charm mean it falls some way short. It's not terrible but neither is it memorable.
Lynden Barber - sbs.com.au
A charming spoof of cold-war alien paranoia, this is visually inventive and full of action, but could do with more humour.
Cosmo Landesman - Sunday Times (UK)
A thin joke becomes attenuated to breaking point.
Philip French - Observer [UK]
Well and truly aimed at kids, Planet 51 is a film they will thoroughly enjoy yet which any accompanying adult will have lots of laughs in too.
Giles Hardie - smh.com.au
Funny and well designed, but doesn't live up to potential due to uninspired dialogue and heavy hand of marketing.
Colin Fraser - FILMINK (Australia)
The screenplay aims wide for every snappy, pop-culture joke that can possibly be cracked. But the viewer's funnybone remains an elusive target.
Leigh Paatsch - Herald Sun (Australia)
Just how much of this will be appreciated by children is questionable, but the film is clearly intended to keep them happy with lashings of colour, movement and cheesy jokes while older, diehard geeks can enjoy all the reference spotting.
Jim Schembri - The Age (Australia)
Little kids who've never seen this story before might get a kick out of it and its bold colours. Parents will be yawning and looking at their watches. At least G-Force dared you to hate it; this just dares you to stay awake.
Michael Adams - Empire Magazine Australasia
I'm going to go out on a limb and say Planet 51 was written by a bunch of monkeys...who were trapped in a room with some typewriters. Surprisingly, the works of Shakespeare are the only texts they haven't blatantly ripped off.
Anders Wotzke - Moviedex
Anders Wotzke - Cut Print Review
There's enough of a storyline here to keep younger space cadets moderately settled.
Derek Adams - Time Out
A hideously annoying and emotionally blank tale.
Kevin Maher - Times [UK]
It's no shock to see Shrek co- writer Joe Stillman on the credits, because Planet 51 follows the exact same formula - slapstick for the kids, sly gags for the parents and a rubbish romantic subplot for nobody.
Robbie Collin - News of the World
It could have added up to something. Alas, any excitement is submerged by the relentless barrage of trite sci-fi allusions and nudge-nudge gags aimed solely at adults.
Sukhdev Sandhu - Daily Telegraph
Silly but not hilarious ... with a message that's so simplistic you might miss it.
Rich Cline - Shadows on the Wall
Alistair Harkness - Scotsman
A jumble of kiddie slapstick and pointless chases.
Jonathan Crocker - Total Film
Glar and his friends are more or less all-purpose protestors, showing up on sidewalks with placards announcing, "We're really upset!" over nothing specific. And that makes them about as amiable and as bland as everyone else on Planet 51.
Cynthia Fuchs - PopMatters
An extremely dull and unfunny comedy with pop-culture references where the gags should be, and humdrum voicings.
Christopher Tookey - Daily Mail [UK]
Good fun if you can put up with the pastel colours and plasticky textures, which show that in modern fantasy animation all that pixellates isn't Pixar.
Nigel Andrews - Financial Times
The laughs come thick and fast in a sprightly kid pleaser full of slapstick set-pieces and memorable characters, while more grown-up viewers will find themselves grinning at pastiches of the Cold War paranoia of bygone sci-fi movies.
Terry Staunton - Radio Times
The action pans out pretty predictably but such is the verve of the story and the impressive visuals you may find yourself heading off course to catch Planet 51.
Tim Evans - Sky Movies
It's frenetic and knowing in the modern manner, though, a couple of good gags apart, not very funny. Its patchiness merely demonstrates the gap between Pixar and the rest of the field - which is the distance between genius and talent.
Anthony Quinn - Independent
Amiable, lightweight fare that adults might appreciate more than children.
Allan Hunter - Daily Express
While pretty much a cut-and-shut of every animated movie of the past decade, this sci-fi comedy should achieve blast-off with the under-10s. For adults, however, this is as solidly so what? as you can get.
David Edwards - Daily Mirror [UK]
There's not a single laugh-out-loud moment in the whole film.
Matthew Turner - ViewLondon
When a film's best characters are rip-offs from other movies. you know you're in trouble.
Jayne Nelson - SFX Magazine
Like the alien town of Glipforg at its core, Planet 51 offers attractions that are just a little too familiar to take the viewer out of this world.
Anton Bitel - Film4
It's hard not to compare, but Pixar's classy and imaginative films set the bar high, while movies like this aim too low.
Russ Breimeier - Christianity Today
...a mildly entertaining, visually well-crafted animation that can wait for rental.
Robin Clifford - Reeling Reviews
Much of the detail will go above the heads of its young audience, but adults will enjoy the clever touches, like the Alien Hotline, the upcoming anticipated release of the movie Humanian 3 and the rock-collecting probe called Rover
Louise Keller - Urban Cinefile
The film isn't terrible if you're, say, six. Because you simply don't know any better.
Widgett Walls - Needcoffee.com
can't quite get over the inertia of its failings
Andrea Chase - Killer Movie Reviews
After all the other animated CGI films this year, Planet 51 just feels like a rehash, and not nearly as charming as it wants to be.
Kit Bowen - The Movie Kit
It's just an excuse for classic-cinema shout-outs and roller-coaster-like commotion.
Nick Schager - Time Out New York
The movie's idea of big laughs is an extended anal probe joke.
David Cornelius - eFilmCritic.com
Perhaps the Spanish-based animated feature Planet 51 should have added a dash of Pedro Almodovar to spice up a rather ordinary revisitation of ET.
Elias Savada - Film Threat
Planet 51 doesn't have enough plot for a 10-minute animated short, much less a 90-minute feature. And unfortunately, what it does have plenty of is crude, lowest-common denominator humor.
Jeff Vice - Deseret News, Salt Lake City
A tale of human/alien friendship, Planet 51 seems worse than it is because it comes at the end of one of the best years in the history of animation.
Chris Hewitt (St. Paul) - St. Paul Pioneer Press
The whole thing is just terrible.
A.O. Scott - At the Movies
dull and lifeless, moving inertly from point to point without offering much that's memorable or amusing
Bill Gibron - Filmcritic.com
After positing its central gimmick, it more or less stands there for 90 minutes, waiting for applause that never comes.
Rob Vaux - Mania.com
If this had been released on Thanksgiving Day or Christmas Day, it wouldn't have been lost in the shuffle.
Linda Cook - Quad City Times (Davenport, IA)
So trivial and unimaginative that, unless you're desperate for sci-fi diversion for the kids, you should wait for the dvd.
Susan Granger - SSG Syndicate
Doesn't belong anywhere near the best animated picture race, but you can do a lot worse when looking for a family flick to pass the time.
Phil Villarreal - Arizona Daily Star
It's cute, it's passable, the animation is fine--but the major problem with the film is its predictability.
Christopher Smith - Bangor Daily News (Maine)
... characters are as thin and unengaging as the animation is sleek and shiny.
Jim Lane - Sacramento News & Review
Children won't understand the '50s-based humor or the references to the creature features that dominated the era, while adults will muster little more than the occasional chuckle
Sonny Bunch - Washington Times
Planet 51 is innocuous to the point of distraction.
Marc Savlov - Austin Chronicle
Stargazers believe there's intelligent life out there. You just won't find much of it on "Planet 51."
Sean O'Connell - Charlotte Weekly
This simply doesn't have the right stuff.
Kevin Williamson - Jam! Movies
Underwhelming alien comedy has some suggestive humor.
Sandie Angulo Chen - Common Sense Media
If you've seen Space Chimps, you can expect the same level of quality. It's not excruciating, but it's entirely forgettable.
Kevin Carr - 7M Pictures
It's good-spirited, and there are enough colorful characters to please its intended audience. Best of all is an Earth-built robot on wheels named Rover, who thinks it's a dog. He'll be a hit. If only the main characters were as interesting.
Matt Soergel - Florida Times-Union
It works for about 20 minutes. And only if you grew up in the 1950s to juke boxes filled with rock and roll including Sheb Wooley's The Purple People Eater
Gary Wolcott - Tri-City Herald
It's fun for the kids, and adults should have a good time too.
Daniel M. Kimmel - New England Movies Weekly
Planet 51 isn't terrible, just bland and predictable as a story, though at least the humor that's tacked onto it is gentle and unassuming...
MaryAnn Johanson - Flick Filosopher
Computers have been assisting in the production of animated films more and more every year, but have they started writing them too?
Brian Tallerico - Movie Retriever
What gives with Joe Stillman, a credited writer on the wonderfully witty Shrek/Shrek 2? Here, his prior expertise in working with lime green characters has inexplicably given way to lifeless gray.
Kimberly Gadette - Indie Movies Online
An often amusing, harmless adventure with enough inoffensive humor and impressive CGI animation to make up for its lack of exhilarating moments and refreshing surprises.
Avi Offer - NYC Movie Guru
A trite compendium of everything that's wrong with non-Pixar computer-animated feature films.
John Beifuss - Commercial Appeal (Memphis, TN)
Planet 51 sucks.
Todd Gilchrist - Sci Fi Wire
Plays to the cheap seats rather than exploring its admittedly clever premise to the fullest.
Scott Von Doviak - culturevulture.net
Starring bright animation and the voices of Justin Long and Dawyne Johnson, Planet 51 follows a hilarious concept with weak execution and way too many references to better films.
Dezhda Gaubert - E! Online
It's all a creepy mishmash of sci-fi and fantasy classics that director Jorge Blanco tarts up with an unwholesome preoccupation with pee, anal plugs, and homosexual anxiety.
Peter Keough - Boston Phoenix
Do anal probe gags sound like fine family entertainment? How about multiple scenes depicting ugly gay panic? Not to worry; a penis joke referring to a male member as an 'antenna' is right around the corner.
Dustin Putman - DustinPutman.com
The film fails at creating characters with credible emotional textures, a task easily, and vividly, demonstrated by Pixar time and time again.
Adam Keleman - Slant Magazine
It is a shame that a movie tweaking retro cliches falls into the white bread conventions itself, especially from a Madrid-based production company.
Nell Minow - Beliefnet
As the umpteenth computer-animated film released this year, it must contend with an over-saturated marketplace. That's one strike. The second strike is that it's not any good.
Eric D. Snider - EricDSnider.com
Parental Content Review
Jim Judy - Screen It!
The movie has little ambition to the creation of its world and even less when it comes to the humor.
Mark Dujsik - Mark Reviews Movies
The story itself is weakly conceived and doesn't sustain a feature-length movie.
Sean Means - Salt Lake Tribune
Largely, it's a jellybean of a movie: bright, colorful, sugary, and with no real content.
Tasha Robinson - AV Club
The animated sci-fi spoof Planet 51 makes you wonder if things might be more interesting on Planet 52.
Gary Thompson - Philadelphia Daily News
This 90-minute movie feels about five hours long.
Matt Pais - Metromix.com
At a time when so many other animated films are actively pushing the envelope, Planet 51 just bottom-feeds.
Tim Grierson - The Simon
A movie so flat and derivative that it seems to have been cobbled together from other, better pictures.
Frank Swietek - One Guy's Opinion
Animated alien entertainment exclusively for those who've already had their brains sucked out.
Chris Cox - Hollywood.com
Independently and internationally produced CG animated comedy Planet 51 has the visuals to compare with bigger budgeted Hollywood studio offerings but not the storytelling spark.
John Hazelton - Screen International
