Actually, I didn't mind the 2004 release. Yes it had some things I didn't like- the ADR with Tamuera Mason, for one- but there was a lot of good thigns in it too. I love the addition to the dogfights, and the charecter footage replacements make the saga flow better, IMO.
Personally, I loved the opening RotS sceane. Agreed, it's nothing like the thrill of seeing the SD rumble over the screen- but their two completely different sceanes. If nothing else, I'd watch the RotS battle over and over again just for the music- John Williams really makes this saga come to life.
