Just got back from seeing The Twin Towers with friends. Jacob T. Levy has a comparison between the novel and the film, and Glenn Reynolds comments as well. I enjoyed the film for the most part, especially since my recollection of the book is so dim that it's entirely possible I never read it. It's a bit like Shakespeare though; you already know the ending (even without having read the book), so ultimately the execution is key. Now I have to dig out my Fellowship of the Ring DVD.
