OF COURSE MOVIES DON'T AGE WELL. THEY WERE MADE 20, 30, 40 YEARS AGO (sorry about the yelling, just trying to get my point across).
But isn't that what makes them so important? That they capture a specific point in history? Similar to a painting or a novel. As I said in the TV thread, I really think we should concentrate on the movies/TV shows that are just as, or more, pertinent than they were when orignally made. As someone mentioned, we shouldn't equate cheesy with "not aging well"
Sorry to be a downer.
