I'm a teenager and I love film (especially the framing, the way music is used, suspense, overall style, and so on). I would become a movie director and try to start making great movies again if I thought it was possible. But from what I've read, movies are a really political thing and you can't just walk in, get complete creative control, and make a classic. If I could actually do that, then I'd go into film in a heartbeat.
Everything's just so smooth and slick and stupid now, with very few exceptions. Everything seems just so disengenous, in my opinion. Movie music also really stinks now compared to before. Possibly because more and more composers are just plugging away at a synthesizer in real time, and not even necessarily writing down their music. (I know J. Williams, Howard Shore, and others are not like this, but still..).
A lot of it is probably that people have changed. How successful would "To Catch a Thief" or "Vertigo" be if they were released today? Not very. And yet they're classics.
Maybe part of it is that what a lot of people find funny in movies today... I don't find funny. He said the F word three times in a row! Ha ha! Ha! Hmm...
