I really enjoyed this one, it was great to see Michael as a kid and get a real explanation of what caused his anger and what led to his psychopathic rage. It was also good to see that he wasn't interested in just going and killing his baby sister (which I never could understand before) and we don't actually know what he had in mind (till she P'd him off at one point).
It's tough to beat an original, but Rob Zombie did a pretty good job here, he gave a real insight into Michael Myers where as the original didn't really provide a background into Michael or any explanation.
