I saw Matchstick Men yesterday, and thought it was a great movie, although the ending didn't quite do it for me emotionally. I read a UK movie review today that put it well:

"You'll come out of the movie unsatisfied and maybe a little angry, but you will have been involved and entertained."

Nicholas Cage is such an awesome actor. I can't think of many as versatile as he is on the big screen. Newcomer Alison Lohman was also really good, and brightened up the screen each time her face appeared. The film was engaging, although, without giving away too much, I wish it didn't quite end the way it did.
