The Turtles: Oh my God, those things were hideous. Dirty Dancing: Why the hell did they remake that movie in the first place. It was sooooooooo bad. Total Recall: Another one that certainly didn't need to get remade. The original was still cool.
Oh, there are definitely more, but can't think of them right now.
Charlie and the Chocolate Factory definitely didn't deserve the hate. It is truer to the book than the original and all of the characters are well cast and well acted. They just had to compete with an already perfect movie. I like both versions, to be honest.
