I've seen a complaint throughout the later half of the 20th century which I don't see much anymore: culture has become "youth culture". It is no longer a common gripe because we can't see this distinction any more. Others here think this is simply the result of a selection bias, but I think it is more than that. Sure, there are still "grown up" films being made, but look at where the cultural moment is and has been -- very much oriented to and catering to youth. The dominance of youth culture is in turn probably a second-order phenomenon, given mass culture and commercial advertising.
