I'm pro-90% of the changes. For example I think almost all the battle shots that were touched are better. I like the Celebration in Jedi, and the extra sweeping shots of Tattooine and Cloud City. The re-done Emperor scene is a very nice addition. I think the Sarlacc mouth is cool. I don't mind Jango-voice Boba for continuity purposes. I like seeing Oola's extra shot when she falls into the Rancor pit. I also like the little changes, like extra troopers and the Dewback in the droid hunt, or adding extra troopers when Han and Chewie chase them down the Death Star hallway.
I am not a fan of the song in Jabba's Palace. I'm not a fan of Vader's NOOOOOO in the Blu Rays. I can take or leave Hayden in the end of Jedi, but I also understand the line of thinking that led Lucas to that change. I don't hate the Jabba scene in ANH, but it basically does the exact same thing the Greedo scene does. And of course, speaking of the Greedo scene, I can't stand the Greedo-shoots-first version, but the recent Blu Ray edit that fixes that crappy jump cut and sort of gives them a quick draw where the shots happen almost simultaneously is alright.
I guess what I'm saying is, there's a few changes I'm not a fan of, but overall, I grew up with the SE's as much as the originals, and the SE's were what I got to see in theaters, and I may not have gotten that privalege had George not decided to do those.
