The Bourne Ultimatum: 8 out of 10.
Like most of you, I enjoyed the Jason Bourne trilogy based on Robert Ludlum's books. I really liked The Bourne Identity, didn't like The Bourne Supremacy as much, and I think The Bourne Ultimatum might just be the best of the bunch.
And just in case I've forgotten what I thought about The Bourne Identity and The Bourne Supremacy, I have this handy, dandy blog to remind me.
