Watched first at IMAX3D then again at normal screen. Felt like a super downgrade but only on the screen size and detailness, 3D just like some other movies, not that much different. Simply go for IMAX if you have the dough. The sheer size of the screen is worth enough. But, normal 3D will be a complete waste I think.

On the other hand, got to admit that those action sequence and fighting scene is quite brilliant but I think too shaky and too fast for my liking especially on the close combat. Barely manage to follow 'em through..
