No, I'm not saying that. I'm saying that the view of Scorsese may be skewed, that his greatness is overrated. Not that he isn't great mind you, just that that greatness is somewhat reliant on the use of violence or its specter.
To which I say Nonsense Poopypants!
Of course I speak as a huge fan, but I think I have put forth enough to show that Scorsese's greatness surpasses the "violence crutch" and there is so much more to his film making capacities. But you seem to have a different view. Which is is fine.
But I wish to ask a question. If a director is known to be great for a certain kind of movie... so what? Does being known for a certain kind of movie detract from a director's greatness? I say no.
Alfred Hitchcock is one of the all time great directors. His influence is far reaching and has influenced many different filmmakers. He is also best known for his psychological thrillers and his later horror films like Psycho and The Birds. Does that mean he is a lesser filmmaker? No. He rose to the the top by being the best at what he does. He made Vertigo, Rear Window, and Psycho. Heck a good chunk of his filmography shows up on the AFI Top 100 Thrillers list.
What about Mel Brooks? The man is one of the funniest human beings to EVER walk the Earth. The man made comedies that were spoofs, satires, and farces. And he excelled at that.
Not every filmmaker has to be a Kubrick who can do an arguable masterpiece in multiple genres. Not everyone can be the walking encyclopedia of film knowledge willing to do other kinds of movies like Scorsese. Not every filmmaker can rise to the level of an Akira Kurosawa when it comes to a filmography. Mel Brooks is very popular for his comedies, people love John Ford's westerns, and people really like Tarantino's various movies with graphic violence. My contention is if you are really really good at one particular kind of film and are highly successful at it, who cares? It should not take away from how good you are as a filmmaker.
