Movies have become more derivative every decade since the motion picture camera was invented. This is the "low hanging fruit" observation.
People only have a certain number of desires, and only desire a certain amount of change. As it gets more difficult to come up with something new that people like, something old will get repeated more. As there gets to be a longer history of "something old that people liked", something new will be created less often.
It's not just movies. You can see it everywhere. Consider, e.g., software. A new edition has to change something noticeable, but it gets harder to come up with something new that people will like as much.
