I agree with Scott on trying to sit as close to center as possible. Go early and stake out a good seat. I saw the movie twice over the holidays and the first time I sat in the middle of the theater and the 3D effects were really good. The second time, we sat off to the side a bit and some of the images and effects just didn't look right.
