I was entertained for all 3 hours of it. I don't care that the plot was thin or predictable. The story moved along very well and the visuals were amazing.
I tend not to go to movies for the purpose of contemplating deep messages, though. Wasn't it Eddie Murphy that said he was just going to keep making stupid movies because people came to see them, despite the critics panning him? I think I'm in that camp. Now if you'll excuse me, I have to go watch Spinal Tap, all of the Die Hards, Lethal Weapons, and a few Farley movies.
