I have 2 tickets for the 1rst week and I plan on going one more time at the second week... Just to clear my head a little bit in between. I also think it will be nice to read all the comments of the fans and then see it one more time...
My opinion: It's the one and only chance to see him on the big screen, it will be like he's there with you or probably "on stage". As painfull as it may be (and it will be for sure, I was very sceptical at the beggining, thinking about not going) I think that the fans should not miss that chance.
If you don't want to go after all, just leave an open window for the second week, read the fan's reviews and then decide.
