Sorry, but it did. I read the book first, which was absolutely priceless. It was the journal of James Simon Kunen (called Simon in the movie), who was a jock at Columbia when the student uprising got started, and half-heartedly joined the protestors, mostly because the squares weren't meeting his needs. He had a wonderfully cynical, pessimistic attitude.
So what do they do for the movie? First they change the setting to San Francisco! Why? Then they make his character into a complete wimp; I cringed at almost every line. And they add all this gratuitous violence, despite the fact that there was almost no violence in the real-life uprising. What struck me about the book/journal was how disorganized everyone was. The protestors didn't have a clear plan. Some of the Columbia students opposed the protestors, and *they* didn't have a clear plan. The cops were powerless to do much of anything to the protestors except occasionally put handcuffs on them and herd them around, and the administration flipped back and forth constantly between trying to compromise with the students and threatening to expel everyone. What I got out of it was that revolution sounds like a great idea, until you get into the dean's office and realize that you don't know what to do, besides pose for a photo in his leather chair while holding a joint.
But that doesn't sell tickets. So they have a big, loud riot scene, ending with a totally campy freeze frame. (I was waiting for Bruce Davison to die in that manner when I saw him in X-Men! No such luck.)
