Things I'm OK With:
Fixing shoddy light saber effects.
Fixing the puppeteer's Wampa arm.
Removing visible matt lines from around TIE Fighters.
Increasing contrast on rear-projection and blue screen effects shots.
Things I'm NOT OK With:
Greedo shooting first.
Any added "restored" shots (I'm looking at you, Jabba Jr.)
Any added CGI.
Any NEW shots.
