i'm with jerseyart on this one. of course, it's often true that a good book will not end up as a good movie. there are notable exceptions...the godfather, for example. considered one of the greatest films of all time, but i don't think the novel itself was considered all that good. maybe that's an assumption though, because i've read one of mario puzo's other novels (the last don) and it was an utter piece of horseshit.
anyway, i like watching films after having read the books that they're based upon, so i can compare. but it's usually a disappointment for me.
i've read the bourne identity and the bourne supremacy (and a few others of ludlum's)...he's definitely considered a legend/master when it comes to this genre. the books themselves are good popular fiction, page-turners if you will, but not my idea of really good writing.
as for the movies...when i saw the bourne identity...my reaction was almost immediate and strong. that movie sucked. matt damon could never play that role, he's just wrong for it from the beginning (too young, for starters). his delivery of lines is great...for an average kid. and the way they changed the storyline was too much for me.
i'm sure this one will suck too. it can't be helped. good fight scenes and chase sequences perhaps...
