While this is true, there are diminishing returns. Part of it is the movie system that exists doesn't reward creativity and risk-taking in the way it used to. It's similar to the music industry. On the one hand, you can make a movie for peanuts, because you don't need to buy film or an expensive camera, you don't need to hire a professional editor even. You could essentially make an entire movie with your phone. But to get eyeballs on it you need promotion and distribution. On top of that, now we have high quality television that pulls creative people away from making films and dilutes the pool of good to great movies that are even considered.
There are always going to be some indie movies that are really interesting and different, but we aren't seeing a lot of real classics that feel like they will stand the test of time. Last ones I can think of that were on that level were in the mid-late 2000s. Maybe some of the more recent work from Tarantino, Scorsese, or P.T. Anderson will have real staying value, but on the order of, say, Casablanca, Seven Samurai, or Star Wars? I'm not so sure. From the '40s through the early '80s there was classic after classic hitting.
Having said all that, there are ebbs and flows in film, and there were periods in the past where at least American film wasn't all that great. The mid-late '80s was pretty pitiful, and in the '90s filmmakers like Tarantino, the Coen Brothers, and David Fincher helped revitalize things. So, maybe that's on the horizon once people have simply had enough lame comic book and jump scare horror movies.
