None of them really. A couple of Death Star battle shots from Ep. IV but the quality of those shots were so inconsistent with the original footage that it was more annoying to watch than anything else. Also scenes in Ep. IV that SHOULD'VE been changed weren't, e.g., Ties chasing Rebs in the trenches. One moment Ties but no Rebs, next moment Ties fire and Rebs just ahead explode to kingdom come. I also hate the remastered look of the SEs. They look nothing like the films from their runs during the late 70s - early 80s. The contrast levels are nice but overall it's just so damn revisionist.
