The Bourne Ultimatum. I really liked this movie, in fact I liked the whole series. Rene and I rented the first two movies before going to the theater to see this one. That turned out to be a good idea, although not really necessary.
Unlike so many sequels, this movie really is a continuation of the last one. The three movies really tie in together perfectly. It's like they are all one big movie. In fact, these three movies work together like the "Back to the Future" series works together.
Definitely a single shot. The entire series, taken as a whole, is a double shot.
The Bourne Whidbey Ultimatum.
