With such high aims, it's too bad that 'The Secret Life of Walter Mitty' falls somewhat short of greatness. But it's not often that you come across a "big" movie as earnest and patently un-cynical as this one.

Stiller's attempt to braid together introspection and humor kept me engaged and curious, even when I wasn't quite sure what he was setting out to do.

The Secret Life of Walter Mitty probably succeeds on its own terms. Given the elusive nature of those terms, it is, however, hard to tell for certain.

I admire the film’s originality, and the thought-provoking twist ending, but daydream of a deeper director’s cut.
