I agree. It had some lengths, but I liked it. There were some pretty cool stunts in there. It did feel more like a set up for things to come than a movie standing on its own two feet though.
I have to admit I've never been a Bourne fan per se. I saw the previous three and liked them well enough, but I always thought Matt Damon too bland, so I don't know how a real fan of the series is going to feel about this one.
