I couldn't give it 5 stars, only because the first Ironman was a tad better than the sequel. I also feel that Jon Favreau should either stay behind the camera and just direct or actually get in shape (if he is going to attempt to portray a body guard). Previews will never sway my ratings of movies I've seen, I just want to take a moment and inform movie fans, that the promise of the Super 8 preview is hogwash. The "preview" showed a train crash with a bulging train car. I am getting very tired of the movie industry empty promises when it comes to this type of preview. So much so that I will boycott spending my hard earned money to see this in a theater and I hope others will too. Okay, I'll step off my soapbox now. BTW - there is a teaser after the Ironman 2 credits, so hang out for a few minutes for the credits to roll.
