This fourth installment in the F13 franchise is arguably the best sequel in the series -- and I can't disagree with that. Corey Feldman's Tommy Jarvis is basically every kid who liked horror movies. I was always extremely envious of Tommy and his room and just everything he has, really. So naturally, it's awesome in the finale when Tommy decides to "become" Jason in order to defeat him. Helluva ending (well, for now...).
