After only having viewed the prequels so far, I finally got around to delving into the OT on Blu-Ray this past weekend...watched ANH and I have to confess that I wasn't really that bothered by any of the changes. Maybe because I have seen the SEs so many times now, who knows, but Obi-Wan's altered screams and R2's CGI rocks didn't really make a big impact on me. I mentioned Obi-Wan's scream to my 16 yr old and he was like "What? He always made that noise", he didn't even realize it had been changed. Of course, he hasn't seen the films as many times as I have, but it was the first movie he ever "watched", the night we brought him home from the hospital, and has probably seen it in the double digits by now. I actually kind of like the R2 thing, even as kid I remember thinking that wasn't much of a hiding spot for R2 and wondered why the Tuskens couldn't see him there...then I just figured either A) They didn't care about droids or B) They just hadn't gotten around to him yet. Other than that, I think it looked pretty nice over all and sounded great. HAven't watched the other two yet, but plan to soon.
