I'm new here, so here's my take on both SEs with bits I approve of and ones I don't.
Approved:
- Enhanced spaceship effects
- Film restoration
- Improved wide shots (Tatooine (not Mos Eisley), Cloud City)
- Temuera Morrison's voice added (it's more badass and threatening, it's like Morrison is Keaton and Wingreen is Bale, Wingreen's was too over the top, but Morrison's was perfect)
- New Cantina creatures
- Fett flurting
- Ewok celebration
Uneven:
- Dewbacks
- Sarlacc Pit
- Mos Eisley (adds scope, but the creatures were too show-off-ish)
- explosion rings
- Emperor in Empire
- Jedi Rocks
- Extended Vader shuttle scene
Disapproved:
- Greedo shooting first
- Luke scream in Empire
- Hayden in Jedi
- Wampa
- Jabba in SW
