"Frailty" was quite a surprise. At first it was very intriguing. Bill Paxton's character is a father raising two boys by himself. They're very happy and then one night the father enters the boys' bedroom and tells them that an angel has visited him and told him that he is to kill demons disguised as humans. Then he turns out the light and exits the bedroom leaving the boys even more in the dark. From that point on the movie is brutal and violent. It's not overly gory, it's just tough to watch because of the way Paxton's character brings his boys into the demon-hunter role. The hardest part to watch is the father trying to get his sons to kill the demons with him. As the story was building, I got a nagging feeling that this was and had turned into another run-of-the-mill religious wacko killer story.... But then...something happens. Something unexpected. Something that turned the movie into something memorable. Many won't like the ending but I think it really saved Paxton's first directorial effort and excellent performance.
