I really like to old movies. Not because Mark Hamill is such a great actor, because he isn't.
For me the old Star-Wars is a milestone in science-fiction. It was ahead of its time but most of all I liked the magic behind it. People going outside an hammering on things to get the right sound for lasers. Doing pyrotechnics to get the explosions right. Building computers to get consistant camera movement during stop-motion. People building Millennium Falcons in different sizes. Layering massive amounts of asteroids. So no computer shit but everything hand made by pioneering teams. For me there is the magic from Star-Wars, hand-made by humans.
There is no magic when I had to see Jar-Jar and crome textured space ships. All I had thought of was the fact that there was sitting some bored dude behind some CAD desktop who did the computer animations.
Another milestone was Avatar, a lot of real human work and input, computers used getting it on the screen. Also the first (full) CGI movie creating realistic characters and everything going 3D. Not comparing it to Star-Wars but it was a milestone.
I'm not saying that the new movies should be hand made by the production teams burning their fingers because they forgot the play with fire (although it would have its charm) but it should include the epicness of PEOPLE creating a milestone and not a 13 in a dozen Sci-fi flic.
