After seeing the trailer, I made an extra effort to see it in IMAX 3D when it was playing. I'm really really glad I did, it was fantastic. Although the non-concert stuff was utter nonsense, the concert footage (along with the audio, which was LOUD) was awesome. It was easy to forget it was just a movie, it was so immersive. I had to stop myself from applauding after "One." And the live staging was very creative, not just a band up there performing. Based on how much I enjoyed it, I ended up getting it in 3D earlier today, though I'm under no illusion that the home experience will measure up to the theatrical experience. Unfortunately, they chose to sell 2D & 3D as separate editions; I would've preferred a package that included both, but at least Best Buy's price for each was reasonable.
