You know, I don't have a widescreen TV, so the lack of anamorphic enhancement, although it means lower resolution, I can deal with it for the time being. And all I have to say is that despite the aliasing and the minor edge enhancement and the grain.... I wouldn't have it any other way. Sure, I like the PT and the SEs, but I don't think I'll be going back to the SEs unless I have some sort of six-film marathon. Without so much distracting CGI and the incorrect color (I HATE that!), I was pulled back "into" Star Wars for the first time in I don't know HOW long.
When I get the cash, I will certainly be picking up ESB and ROTJ. ESB, mostly because of the correctly colored lightsabers... the borderline pink saber nearly ruins the Cloud City fight for me. ROTJ.... I cannot stand "Jedi Rocks" and although I can live with Hayden, it's his performance in the scene itself that bugs me. He doesn't look inviting at all, and once again, the murky, ugly Lightsabers are too much, I can't focus on the fight because of it.
So sue me, I even like the grain. A small wash to remove some of it would be nice, but I'd like some grain left in. I totally understand what people mean when they say it adds charm... it totally does.
The only things I'll miss from the SEs are the digital recompositing and most of the SE Death Star stuff for the Battle of Yavin.
