Not to go all spoiler on you, but do yourself a favor and watch "The Bourne Ultimatum" for these two reasons: a car chase sequence and a hand-to-hand fight sequence. (There's a third reason too: a chance to revisit some of the environs of the 1937 French classic, "Pepe Le Moko". Now that is a GREAT genre film.) The rest of "The Bourne Ultimatum" is very enjoyable, and yes, it is a 100% genre workout (but don't let that scare you.)
My only complaint about the film is its screenplay's reliance on awkward exposition. You know how that works in spy movies, right? For half the movie, you will hear every character make references to a secret operation ("Operation MumboJumbo") without providing any more details. Then at some point in the film, one of the characters will start describing Operation MumboJumbo's goals for no reason other than to bring the audience up to speed. I know, I know, every genre has its beats and a good film has to hit those beats.
