At first, I wasn't in the least bit impressed with this film. Mostly, I was disappointed by Wes Bentley's rather wooden performance.
As the film rolled on and the storyline became more complex, I began to quite enjoy this film. By the end of it, I gave it a 4/5 because the twists and surprises really were quite good.
Unfortunately, even after seeing "the making of", I am still not impressed with Bentley's performance.
