Ok, I've seen episode 7 and it is awesome. I'm probably going to go and watch it again, but this time for "free" with my Cineworld pass.
I'm currently (as in right at this moment) watching Doug Walker's Disneycember video about the special editions of the original trilogy.
He's mentioned a few times about he's ok with the idea of an artist going back and adjusting their work. The thing is, this doesn't sit well with me for one simple reason: George Lucas didn't direct The Empire Strikes back or Return of the Jedi. By making the special editions he is going back and 2/3 of the time changing someone else's work to fit his own "vision", and his vision is (in most cases) inferior to the vision of the actual director.
