I caught it last night and it was pretty good. I still like the original more, but this one was funny. I may not care for Depp personally, but he is a great actor. My wife and I looked at each other at one point and agreed that Depp as Wonka seemed like Depp as Michael Jackson. He was pale, creepy, weird, had his own amusement park and had a thing for boys. The comparisons were uncanny.
There are some things that were different from the old vmovie and book. I don't want to spoil anything so I'll not go into specifics.
