Saw the film with my wife. I thought it was amazing. The memories from the songs, the musicians, the lighting and pyro,the gear, the dancing, all great.
As to MJ not looking as sharp, I had a different take on it. It looked to me like he was doing a walk through and also thinking about "maybe if I do this and not that, or if ...." always looking for a way to make the production better.
I didn't like all the yes men around. IMO, I think that was a large part of his problems, nobody wanted to tell him no.
I hope that they release this on DVD with a full dress rehearsal at the end. I'd buy it.
