I really like both movies, but the simplicity of the story in first gives it the edge for me. There was something really refreshing about how bare-bones it's plot was, yet it still managed to have some heart to it. The second introduced far more of a story, and while I wouldn't go as far as to say that hurt the film, I definitely missed the stripped-down feel of the first one. It also lacked the simple but effective emotional connect the original had.
