I think what you're getting at is that novelty is being sought as a (poor) substitute for real substance. Give me a movie made by someone who has really thought about an aspect of the human condition and explores it from their own point of view, and it will have true originality and keep you riveted, even if the theme has been treated thousands of times. There aren't that many different themes, but they are inexhaustible if treated well. Movies bore us not because of lack of novelty, but because they're just tropes stitched together to fit a formula rather than representing a real creative endeavor.
