The Intro to the film, "One Flew Over the Cuckoos Nest" comes to mind.

Great film, slow, steady, meaningful.

Do the people who have their phones out in films nowadays watch those old movies without looking at their phones, hmm?

Your snark makes you sound like an arsehole.

Bud.. people are on thier phones constantly.. there nothing that will stop that..

The fact that classics exist has literally nothing to do with this discussion. Also, no, movies aren't getting longer. Source.

There are plenty of great films still being made every year. If you don't watch or like them, that's a you problem.
