This is a visual masterpiece that can only be portrayed in 3D. I had some initial trepidation about going, due to the cheesiness of the 2D commercials and posters, thinking it was going to be just another cartoon. But after seeing it in IMAX, and in 3D, I realize there's just no way to represent it in any other format. The reviewers who take pot shots at what they consider to be a thin plot line are missing the point-this is a visual experience, not a James Joyce novel. See it.
