We just got back from seeing The Bourne Supremacy with the Barnes.  It was really good, but they went way overboard with the handheld shots.  There were lots of the movie where I had to look away to keep from getting a headache.  Other than that it was really awesome.  I was pleasantly surprised to see the actor who played Eomer in the Lord of the Rings.

My advice is to sit toward the back of the theater unless you like motion sickness.  I really think the director, Paul Greengrass, could have conveyed the same effect without so much camera shake.  It was really distracting.  But, really, it was awesome.  I love that kind of movie.
