I didn't mind Depp as much as Rodzinski did. But the squirrel scene alone was worth seeing the movie!
While I would say it's far from the best movie I've ever seen, I really enjoyed Charlie and the Chocolate Factory. But then I've always been a Willy Wonka fan and loved the Gene Wilder version. I heard enough before I saw it, (including a "How they made" show in HBO) to expect something completely different from Depp's Wonka and had heard that this version is darker and much closer to the book.
I've always thought Willy Wonka has to be an extremely strange character to have a chocolate factory like that, (what would you be like if you'd been secluded in a factory with just oompa loompas for that many years!) so I didn't mind Johnny Depp as Willy Wonka at all.
It's a bizarre story and the movie is bizarre. I had already heard it was like being on acid when you're sober, so I was looking forward to the visuals. I really didn't like the additional back story about Willy Wonka's childhood, and thought that detracted from the story. I also prefer the ending to the Gene Wilder version better than this one. But I enjoyed it.
The Squirrel scene is a kick. Did you catch the very quick Edward Scissorhands moment near the beginning?
