the Bourne Ultimatum was pretty damn amazing, guys. Highly recommended if you like non-over-the-top-retarded-but-still-intense action thrillers. Also an excellent wrap-up to the series, they managed to work within the established mythology of the series, move and even complete Bourne's character arc, while still leaving a lot of stones unturned. I loved all the moments of reference to Maria in the film, such as when Julia Stiles dyes her hair and you can tell that Jason is remembering that moment from the first film, even though they don't flashback.
I hope this is the last Bourne movie, but if they do a sequel it should be called "Webb of Intrigue"
