Just got out awhile ago. I enjoyed watching both concert movies a lot, but I wish their we're more people. The theater wasn't really that packed as I thought it should have been... Anyways I loved Rock'n'Roll Circus a lot more then Next Level. I wish they would of never took out Rainy Day.
Edit: Also I think whoever else lives near or in Los Angeles should go to tomorrows screening (If they still have the tickets at the doors) even if they have seen the concert or own the DVDs. It's a really cool experience to see one of your favorite Asian artist in a movie theater in the US.
