Adywan, I love this project!
Man, if Lucas really wanted to update the trilogy, he should really just hire you. There really is no better out there!
I like just about all of the changes. I read about the Obiwan hut dialogue change, and thought I wouldn't care for it... but I really enjoyed it. It actually seemed to flow better than the original. I went back and watched it, and couldn't even tell where the edit was - so well done on that!
The only thing I didn't like at all, was the lightsaber changes when Vader and Obiwan meet.
To me it's very similar to the Solo/Greedo change Lucas made, because it really changes the character of the character. If that makes sense.
That moment is a great illustration of the Good vs Evil idea and gives you some insight as to how the characters are thinking - Vader ready to fight (evil), Obiwan unwilling and defensive (good). Even after he sees Vader he doesn't activate his - only when Vader advances.
I think that changing that around really changes the characters.
Also, seeing Vader just standing there, without saying anything, with his saber already on... it's just a really cool moment.
Anyway, thanks again for all your work. Even if I disagree with that part, I thoroughly enjoy it as a whole. It looks and sounds great, and the rest of the changes are right on! It's incredible!
