6) Luke’s scream. Only used in the 1997 version, and a bizarre addition which was thankfully removed in all future versions. Without this, the 1997 SE would be about neck and neck with the 1980 version for me.
Too bad we now have to deal with Vader’s "Noooo"s at the end of ROTJ (as if it weren’t already the most insufferable episode’s SE of them all), i agree that TESB is the best of the SWSEs, the fact alone that an argument could be made (whether someone agrees or not) if it’s better than the original says it all, but still, the added effects recall too much attention, they really stick like sore thumbs.
I’m actually not against the Wampa because, if anything else was left the same, it would be more like a Lucas’ cut instead of a Special Edition, and i’m all for extended cuts in general, unless the movies in question are awful, but this definitely isn’t the case.
