It's really interesting that you thought that about Goodfellas. I'm not a Scorsese fan at all, and sympathetic to a critical view of him, but I thought Goodfellas was nothing if not entertaining. Raging Bull was aggressively dull on the other hand. Mean Streets might have been good at the time but I found it virtually unwatchable.Put some of Scorsese's works against a Marvel film and I struggle to see this big qualitative difference. Marvel is dumber, less demanding and you don't give a shit who actually made the movie, but if you're looking purely at the pictures, what do you actually take away from Goodfellas or Wolf of Wall St other than being entertained for x amount of time? Not even much at that with Goodfellas, as it's one of the most boring movies I've ever seen.
Raging Bull or Taxi Driver obviously have substance and that impregnates the technical stuff with some kind of transcendent meaning. There you feel a real artistic vision and not just that someone has paid attention in film school.
