Definitely don't read the book first, if you haven't yet. The movie itself was decent, good action, fairly consistent to plot. It irked me that plot points were missing and other things changed rather seriously. The book is NOT a prequel, as this movie kind of implies. In the book, Jack Ryan has already established his character in the CIA, in fact, he's the deputy director. He's married, he has kids. I don't know why they changed that, except maybe due to Affleck's age. Affleck's performance surprised me in a good way. I wasn't sure he could pull off the intensity of this role, but he handled it really well. It's definitely worth seeing on the big screen.
