Looking back on it, a big problem with a lot of the SE revisions is that most of them feel like they were done on the cheap, as half-assed as possible.
In ESB when Leia and the rest chase Boba to the landing platform, the music is completely jacked up and out of sync compared to how Williams originally scored it. Williams could've rescored this (and similarly messed up scenes)... but that'd cost too much.
In ANH, the restored scene with Biggs is so choppy and off-kilter that I have to wonder why Lucas even bothered. If he shot no close ups of the actors to work around the cuts he'd need to use, surely he could've modifed shots from other scenes to make it all work... but that'd cost too much.
In the '97 ANH, there's just no frickin way that CGI Jabba should've passed ANYbody's QC check. But it wasn't redone... it'd cost too much.
In ESB, yeah, we've got the "corrected" Emperor scene with McDiarmid but his make up doesn't look like a good match with ROTJ.
With ROTJ, you've got the "corrected" Anakin ghost with Hayden's head. But it's just Hayden's head. Would it have really killed Lucas to insert Hayden in there properly? Putting aside how unnecessary this change ever was, it looks like a weak Photoshop job. It could've been fixed... but that'd cost too much, I guess.
There are also mattes boxes around a lot of ships, even now. We've got some fairly impressive CGI in some shots... and garbage mattes in others?! Does that make sense to ANYONE?!
There are probably a billion other examples but you get the point.
I mean, bad enough that all this crap ever happened but when it's done so cheap, it adds insult to injury. I realize this stuff costs a lot of money but so do the DVD's. (A) LFL will make their money back and (B) there is such a thing as "the cost of doing business". Certain things cost money in life; do 'em right or get out.
If all of the changes Lucas has introduced could be done in a non-amateurish way and if the original (theatrical) cuts were respected and preserved, I'd honestly have no complaints.
EDIT- And this isn't just the OT. The prequels suffer from this to varying degrees. The theatrical cut of The Phantom Menace had awesome effects in terms of lighting/shadow, textures and so forth. But when Lucas restored parts of the podrace, you go from basically perfect effects in many shots to a couple of shots that had that "slick as snot" quality that everyone associates with CG images.
