I haven't got the time to really write about how awesome U2 3D was. Jen Chaney at Washington Post summed it up pretty well though.
"I have decided to refer to the in-my-face Bono as Hologram Bono. I expect that at some point during the movie he will say: 'Help me, Obi-Wan Kenobi. You're my only hope.'"
"That dude four people back from the edge of the stage? I think he has the same cell phone I do."
"They're doing 'Sunday Bloody Sunday.' And Hologram Bono is not only in my face, he is looking right into my eyes. 'Wipe your tears away.' He is reaching toward my cheek. 'Wipe your tears away,' he sings again. My eyes are notably dry. I feel I have let down Hologram Bono."
"I always wondered what Larry Mullen Jr. keeps next to his drum kit. Now I know: A box of Kleenex and what appears to be a glass of Orangeade."
"It's official: 'Where the Streets Have No Name' is the greatest live song of all time. Okay, 'Born to Run' is a close second. But nothing -- NOTHING -- is better than that slow build in the beginning, then watching the entire crowd bounce in 3D."
I'll add this: There were no just-for-3D gimmicks in the film. While the geniuses at 3ality Digital Production made you feel as much like you were at the concert as possible, they successfully resisted any urges to "throw" anything from the screen at the audience. The only time I thought about moving my head back was when Bono reached out to "wipe my tears away." The rest of the time I just felt something between actually being at the show and having an out-of-body experience (when the cameras were above and behind the band).
I hope you go. It's that awesome.
