The Incredible Burt Wonderstone
Simply put: Burt Wonderstone was hilarious. If you didn't see it, it's probably because it was misadvertised. The advertisements should have shown the relationship between Steve and Oliva. That entire side of the film was far more entertaining and enjoyable than the Jim Carey vs Steve Carell rivalry part of the film, which really does take a backseat to the real story.
The true story of Burt Wonderstone is one of Man vs Self, not Man vs Man. I think many people went into the theater thinking that they were gonna be wowed by Jim Carey, but instead got a heartfelt performance of a washedup arrogant stage magician who humbles himself enough to spark a new era of his career.
Overall, it's worth seeing, but probably not worth paying for the big screen prices unless you're seeing it at a dollar theater. If you're a Steve Carell fan, it is a worthy performance and should quickly find a spot in your home collection.
