I loved ATYCLB, HTDAAB, NLOTH and the Vertigo Chicago concert.
And I saw U23D at the cinema. Somehow it didn't set me on fire, I mean even music -wise.
I think my audio set up at home might sound better than what they had in the cinema, but Bono just didn't seem that energised to me. That aside, I am not a fan of 3D in general, and elect to watch 2D versions.
If U23D was released in 2D (unlikely) I might buy it. But isn't it the same setlist more or less as Vertigo Chicago , and only 14 tracks ?
