Yeah, I guess it's just a matter of opinion. There's a reason I paid tons of money for the non-Lucas-updated Star Wars original trilogy - I always felt there was something magical about everything being a real puppet, costume, special effect etc.
I think a lot of people would probably watch less movies if there were no real actors on screen, just voice actors. Then again, voice actors tend to be much more likable people, so they'd probably have a lot less potential PR disasters...
