I just saw it, and as someone who is a big fan of the book and waited a long time for it, I was pleased with it. It was good, but not great. I don't know why they had to cut the running time so much, there was a lot they left out or covered too quickly. They changed or left out a lot of the cruder and more childish language(like the repeated references to "fart, fart-eater," etc.)) which was a good move. Leaving out the "Demosthenes and Locke" internet subplot made sense.
