The movie whips up a big old puree of ingredients borrowed from other cinematic recipes. Then it dishes out the mildly spiced results as post-Oscar-quality snack food...
Neeson, often chided for cashing easy action-flick paychecks at the expense of his serious-actor cred, knows who he is - an action star of a certain age who brings gravitas to pulpy stuff. And if that's who he is, he could do worse than "Unknown."
It mixes and mismatches jagged fragments of Jason Bourne, Alfred Hitchcock, "Total Recall" and Mel Gibson's underappreciated "Conspiracy Theory," although underappreciation isn't a risk for a movie that amounts to "The Stillbourne Identity."
Turn off your 'I hope this plot twist is awesome' part of your brain and just enjoy big, gruff, increasingly Frankenstein-monster-looking Neeson kicking the crap out of everyone who gets in his way...
With his soulful gaze and crooked nose, his seeming reluctance to throw a karate chop but his deft ability to do so, Neeson has an air of melancholy and menace - you feel sorry for the guy, and wary of him at the same time.
Unknown" obviously knows its limitations, and it doesn't bother to rise above them. It just keeps throwing the punches the audience wants and expects. It won't cure world hunger, but chances are it will sell a lot of popcorn.
