By Ruthe Stein
By creating likable characters and putting them in situations that seem plausible, if a bit of a stretch, the film succeeds where others of its genre fail.

"Maybe" was watchable and blandly pleasant; "Theory" is a smidgen better than that, if not the cruelly funny farce the movie's best impulses and its own trailer would have you believe.
