WARNING: SPOILER AHEAD!!!
I went to see this movie last weekend after my mom and sister saw it and gave good reviews. I wasn't all that interested, but I ended up going anyway.
I have to admit it wasn't all that bad. It was a funny movie, and Johnny Depp was hysterical. The Oompa Loompas were funny as well, doing modernized versions of the old Oompa Loompa songs in new styles, such as disco.
As you may already know, the Charlie and the Chocolate Factory was a recreation of the old Willy Wonka and the Chocolate Factory. I think the whole reason they remade it was to go into a little more detail of Willy Wonka's past. In the movie they show his father, an uptight dentist who never let his son have any candy (and put him in a headgear more elaborate than the International Spacestation), Willy's first piece of candy, and him running away from home to escape his father's rules about candy.
Other than that, the movie is the same as Willy Wonka and the Chocolate Factory and the book, Charlie and the Chocolate Factory. I would reccomend that you see this movie as soon as you can.
