We saw U23D last night at the Imax and it was great! I love 3d movies, and since I saw one like 10 years ago, I don’t know why all movies aren’t 3d yet, but I digress. They made great use of the “one” additional dimension, at times Bono or the Edge are all up in your proverbial “grille” with the crowd unfurling behind them.
Between the great visual effects, which at time moved the stage’s background visuals into the foreground, and the great sound system of the Imax, this was a fun experience. So if you like U2 at all, check out www.u23dmovie.com to find it near you.
