The story manages to be sentimental without being especially moving.
Vincent Canby — New York Times
It looks good, moves well, and delights our eyes.
Roger Ebert — Chicago Sun-Times
Not enthralling, but worth seeing for anyone interested in the mechanics of this arcane art.
Dave Kehr — Chicago Reader
Every character moves fluidly and imaginatively against an extravaganza of detailed background and dazzling effects, all emboldened by fascinating colored textures.
Variety Staff — Variety
It is something gorgeous to look at.
Richard Corliss — TIME Magazine
Fascinating. But sensitive animal-lovers beware.
Michael Scheinfeld — Common Sense Media
The award-winning book had a pretty crackerjack story to begin with, but in some respects, I think Bluth and his co-writers have bettered it.
Tim Brayton — Antagony & Ecstasy
A return to the lush, finely detailed animation seen in the best Disney features.
Dean Essner — TV Guide's Movie Guide
The animation was, as Bluth and company had promised, a spectacular return to old-school craftsmanship.
Tasha Robinson — AV Club
It's a spectacular return to the shimmering, mesmerising deep-focus animation associated with Disney's classic period...
Derek Adams — Time Out
Never mind the G rating, this is scary stuff which sent my little one fleeing to another room inside of 10 minutes.

Lovers of animation shouldn't have too much trouble getting the kids to take them along.
Dean Essner — Film4
Too leaden for kids, too slight for grownups.

It took years before Disney would match the quality of this first film from expatriate Don Bluth.
Jeffrey Westhoff — Northwest Herald (Crystal Lake, IL)
It remains the best entry in Bluth's hugely inconsistent filmography.
