I've seen both. I first saw Bourne Supremacy and my gripes are that 1. Marie is around for less than 20 mins in the movie and her death seems really trivial as a result. 2. The camerman has a seizure everytime action happens. I.E. It looks like an amateur shot the fight/action sequences ala Shakey-Cam. 3. It felt more like a bunch of randomly strung together events- there was no details leading up to a scene i.e. Bourne shows up at place to place w/o any time spent on what happens in-transit.
On the other hand, I, Robot, was a kickass movie with (dare I say it) more Action than BS, better humor and of course a better story in the end. Seeing I, Robot and Bourne Supremacy made me realize just how good the former was and how bad the latter was. Yet from what I've heard BS got better reveiws than IR. Can anyone explain why?

Maybe my information is wrong? Discuss..
