When I read the post you're replying to, my first thought was, "sure, some movies are boring. But I bet they're talking about stuff like Pluribus, not actual boring movies."
Pluribus has no filler. Sure: the plot moves slowly, the cinematography is artsy and sedate, and it's all very character-driven. So what? It's beautiful. You may as well go to an art gallery and say the story moves too slow. Look at the stuff on the screen. Take it in. You don't have to like it, but maybe don't assume that Vince Gilligan is wasting your time with filler to make a quick buck. Consider that you might be holding it wrong.
