First off, 3D is a cool novelty for about 10 minutes, and then I wanted to throw the glasses away. It doesn't enhance the movie in story or the way it relates to the viewer. It just looks cool on a few scenes. One-size-fits-all does not work on glasses. Get over this novelty, Hollywood.
Ok, Johnny Depp is a great actor, but lately he seems to play the same character but just in a different costume. No big surprises there, and as with the whole movie, there were no surprises. They told you what would happen and nothing deviated from the plan. Very predictable movie.
As a big fan of Lewis Carroll's work, it was an enjoyable movie. It looked great and had some funny lines. Tim Burton meshing with Disney is an interesting concept.
