You would think it would be good... It had old characters, new ones, and its in the 80's! Buuuuut it's not. Was this X-men or a cheap Hollywood disaster flick? I also couldn't get over how overdressed the villain was and how he Tailored for the other villains. I also feel they made a bad a choice for Jean gray... She lacks the "bad ass" quality the JG/Phoenix should have. She looks like about to cry all the time. It's ok not as good as "day of futures past" so don't get your hopes up.
Its 2h:27min you can take 2 bathroom breaks they will still be tearing down cities and shit.
