Well if you are picky then you can apply "majority is trash" to anything... films, anime, music, food, etc.
Unlike many people who say "older films" are intrinsically better, I think the majority of films in general are not good (= not to my liking). "Older films" have the advantage that there is much bigger pool from which I can make the selection and therefore there are more I like. But I would say the percentage is the same if I compare it to the most recent films.
