THX and Graffiti are two that have always puzzled the hell out of me. What was the reason for that singular CG shot at the beginning of Graffiti? Would it have really made a difference if he'd not bothered with it? Did he just want to leave his signature on it? Hi, I am George Lucas, I put CG in all my old films!
I really like to watch older movies with the period it was made in in mind. To view them as a product of their era. I will watch a bunch of movies made within just a few years of each other and take note of the styles and trends popular at the time. Behavior like George's really knock this out of wack and irritates me to no end. And for what? Yeah, nobody can really say. Err, yeah, George updated American Graffiti because... well, because... er... huh. THX 1138? Yes it was imperative George added CG effects to this film, because it was so outdated looking and it would make it more acceptable to the masses. Nobody likes THX 1138, and the types that do like it and watch it are not the types that get bored unless they are wooed by colorful CG graphics and explosions (like the masses of new "SW fans" who think ANH is extremely boring, but ROTS is the end all be all).
