Not a fan of the new "changes" so I won't be watching them on Blu-Ray anytime soon. And same with the 3D movie releases... not my thing.
I've never dressed up as a character, but I do love the lore of Episodes IV, V, & VI. I don't care for the extended universe things except for a few of the videogames. Other than that, the Prequels are lame and George Lucas doesn't know when to stop changing his movies.
He needs to stop trying to "upgrade" his films... heck Spielberg realized he made a mistake in changing guns to walkie-talkies, so why can't Lucas see the same thing? New doesn't equal better. Nor does CG always equal better. Real Steel was more convincing as a movie than any of the Prequels. Lucas is a terrible director and a bad story teller. He had a great vision at one time, and is responsible for the fantastic work of Skywalker Sound, but he needs to know when to let things go.
