I was surprised with this movie. It is much better than I thought it would be. Charlie Sheen's acting track record isn't great and he starts off quite bad (trying to imitate his dad in Apocalypse Now, sort of?), but he starts to act appropriate to the role after about twenty minutes. The film has the right pace for the genre and it isn't boring as one reviewer has written. Worth your time.
