Why is john there in the first place?! I really enjoyed this movie and my wife tells me that the answer to this question is "otherwise there would have been no movie!" While she is correct, of course, there is still a little issue for me of the whole of LA and poor John finding himself on this detectives doorstep. This film is wonderfully acted and has a very compelling story. It kept me guessing and kept me intrigued. Its a really unique story that turns your ideas of "bad" and "good" on their heads. I recommend it but just don't expect to understand its origins. There is no logic to be found there and attempting to find any is just going to disappoint!
