The visuals were very much worth the IMAX 3D and you felt like you were actually in it. It was just as you would always imagine wonderland to be.
The story was good, but would have been better if Alice's character didn't seem like she was high and had attention deficit disorder at the same time. Her acting was atrocious.
Johnny Depp was amazing as usual, but at certain time you could not understand what he was saying because he would switch accents. I think that was intentional though.
Helena Bonham Carter was most definitely the star of the show. She did a fantastic job playing the red queen and was quite comical.
Overall, it was an enjoyable experience. I'd go see it again, but not acting, for the story and visuals.
