Geeze... Why would anyone even do that? Make a 2D version of a 3D concert that is blatently marketed as 3D. Just stop. Don't fall into this trap fellow 3D fans. Run away from this one!
Much like "Man of Steel", this movie is too concerned with loud fight sequences than drawing you in to care about the characters. I may warm up to it more after a 2nd viewing, but my initial reaction is that we have another "average at best" comic book hero movie. I'm also a big fan of 3D, and the Ultimate edition is 2D... Really???
