Here's my thoughts on each change in the SW Trilogy SE, as http://www.theforce.net/swse/ lists them. It's the most complete listing I could find.
- GOOD: I actually quite like this change. I just think it looks cooler.
- BAD: Completely unnecessary. The original scene worked perfectly.
- BAD: See above.
- GOOD (referring to general landspeeder shots): I never liked the damn green glob.
- BAD: Why is smoke coming from the chimney when he lives on a planet that's hot as hell?
- GOOD: Kinda nice to see the Death Star move.
- BAD (General Mos Eisley changes): The near-ghost-town feel was so much more atmospheric...
- MEH: Good in that the original shot sucked, bad because those "scurriers" are stupid...
- BAD (general Cantina changes): Mainly the replacement of Wolfman while Penis-Mouth still remains...
- HORRIBLY WRONG AND SHITTY: Do I even need to say why? The scene lost its entire reason for being when this happened....
- BAD: Everything in this scene was covered in the Greedo scene. Plus not seeing Jabba till Jedi was much cooler. Plus the CGI sucked and still (2004) sucks.
- BAD: Overuse of CGI.
- BAD: The update of the explosion was OK, but the Praxis ring was a bad idea IMHO.
- UNDECIDED: I kinda like both versions...
- BAD (thrusters): Overuse of CGI again...
- UNDECIDED: Can't remember the original shot...
- GOOD: Gives him something to look at. Don't think there was anything before.
- GOOD: Much improved over the original. Has a more "earthy" feel.
- EXCELLENT: The single BEST CHANGE of any of the SE's! Makes his death (more) meaningful.
- BAD: Overuse of CGI...yet...again....
- BAD: Overuse of CGI...the old shot was fine...
- GOOD: Never liked the straight line before...
- GOOD (general DS attack changes): Much more exciting and tense than the original.
- BAD: See the destruction of Alderaan.
- GOOD: Never noticed this was a change...that's what every one should have been, at least seamless enough so if you'd never seen it before you wouldn't be able to tell.
- GOOD (JEJ gets credit): Why wasn't he credited before?Well, that's it for now; later I'll post for ESB in this same thread and then ROTJ later on.
