Before seeing this movie I had really wanted to see the concert at the O2, now I want to see it even more. It's too bad that MJ wasn't able to put it on, it would have been the best concert ever.
For my taste, the movie was a bit too short. I really wanted to see the Billie Jean outfit (which was mentioned but not shown) and know what song the chandelier was for. Also, I think it would be awesome if they put on and recorded the show w/out MJ, just so we, the fans, could see what it would have been like (well, it would have been more amazing than that, but still).
