Charlie and the Chocolate Factory
I thought it'd be crap, but I came out thinking it was OK. A lot of that is probably due to Roald Dahl's great story (I never read the book). I also found myself thinking "how depressing that the brats remind me of four out of five actual children in 2011". 
The original or the remake...?
The original is amazing. I've probably watched it more than just about any movie, alongside Nightmare Before Christmas and Forrest Gump
I know this will probably get me killed, but I really like the Tim Burton version. It's not a remake at all, it's an adaptation of the book, much closer than what the original movie set out to do.
I love both films. The original is clearly more close to my heart for obvious reasons but the Burton version is still great.
The one area the original is best at are the songs and choreography during said songs. It's a much better musical, so to speak. In the Burton version, all of the Oompa Loompa's are cgi of one dude, and it lacks the panache the original had. But if you like the book like I do, the Burton version is worth watching.
Still my favorite song in a film music:
