Yes Man is a pretty dumb movie. There's enough plot holes to drop an elephant through and most of the things Jim Carrey says "yes" to are artificial, unbelievable circumstances. I mean, if anyone said "yes" to everything, it would most likely result in lots of overtime and unwanted family dinners. The whole thing is implausible and nonsensical and at moments, inappropriate. And for all of those reasons, Yes Man is enjoyable. It's a light optimistic comedy that contrasts itself against a film industry that takes its work all too seriously. Check your brain at the door, order take out, and laugh a little. It's a mediocre movie, but it's pretty darn good at mediocrity.
