The two things I found most distracting/annoying about ANH:R were
-Additional Wilhelm screams. That scream takes me right out of the movie because it is heard EVERYWHERE and is not unique to Star Wars. In fact I was hoping it would be removed when Chewie throws the Storm Trooper off the carbon freezing deck.
-Overly bright/colorful laser blasts. Just because they are in the PT like that doesn't mean they work in the OT. Consistency for the sake of consistency is not always the best idea.
I am hoping these two aspects will be dropped for ESB:R, as they made ANH:R unenjoyable to watch at times.
