well i really liked the movie. the book is probably a lot different though.
It's so different that I swear, at some point, the director or screen play writer just took the book, threw it out the window, and just started making it up as he went.
i actually don't have a problem with that, as long as the movie is good. i liked the movie, i'll probably read the book at some point. like the bourne identity books and movies are completely different, there's really only a few similarities in the story.
