I think some of it may be that everything is too big now and they all have too many options they can, relatively, easily take. When special effects became easy every movie turned into an action movie. Special effects are everywhere creating scenes that don't actually help tell the story or develop a character. It just seems like there aren't hard choices being made to force a movie to be its core best self. Every scene should matter. Of course we can't go back though. I don't think many people would pay to see the something like Jaws again.
