I’m going to guess you’re on the younger side. You’re going to find a lot of these older movies boring. They take their time in a way that newer movies don’t.

I find A Clockwork Orange to be a boring slog of a movie full of cringe gang slang and stupid outfits, but the deeper message of the movie that ultimately life is about freedom of choice even if that choice is to be a complete piece of shit holds up even to this day.

The Shining might not be a movie you’ll want to see again, but from a filmmaking and storytelling sense, it’s lauded because of the attention to detail that went into the clues etc in the background. Sometimes a movie is more than the sum of its parts.
