If you ever read Roald Dahl's "Charlie and The Chocolate Factory" you will see that the story is not as scary as it's presented. The oompa loompas are so creepy (amongst other things) that I wanted to cry in the very first scene they appeared. But well, it's a Tim Burton's movie. What else to expect? Sometimes it works, sometimes it doesn't. In this case he ruined one of the most heartwarming stories I've ever known.
