"Truly novel" is kinda difficult to define requirement. With literally any movie, you can argue for hours whether it was truly novel or not. But for me, just browsing netfix got me much bigger variance then what was available to me 20 to years ago.

Back then, all films were the same action movie plus some comedies, basically. They all ended well. There are good and bad characters, no nuance and good ones win. The structure was also the same and formulaic.

You could go to indie theater and see something else once in a while, but that was it. I have seen more novel things (at least novel for a movie). Not all of them were well executed, but the writers at least tried a new idea here and there. Twin sisters that switch families every year for example. It was not too good, but was not too bad and mainly it was something different.
