If it seems like there are a lot more bad movies today than, say, 40 years ago, it's because there are. But that's because there are a lot more movies being produced every year.

The data is apparently from IMDB.
40 years ago, a lot fewer movies were being made. That means the pool of scripts that passed muster was a lot smaller, and the quality of the average film was likely to be better than it is today with today's flooded market. That doesn't mean, however, that they aren't making good movies anymore. It just means that there are a dozen bad movies for every good one, instead of three or four.
But yeah, anyway, to argue all movies that come out anymore are shit is asinine.
