I so agree with you on Raimi. The men who are the best comis book directors are Deltoro and Chris Nolan. They are great directors. Raimi is ok but has not there talent. Why does everyone love Polanski and Scorcese. The Depated was good but i Think Spielberg and Eastwood are better then them.
I haven't seen a Polanksi film, but I can easily explain why Scorsese is so loved:
-He's made some of the most influential, controversial and analyzed films in cinema.
Taxi Driver, when it was first released in 1976 was quite groundbreaking for its time for its subject matter and its depiction of certain "taboo" topics (such as the relationship between Travis and Iris). To this day, film students all over the world still study it intensely, especially its ending.
-His camera work is incredible. Watch the fight scenes in
Raging Bull, or the scene in
Goodfellas where the camera follows Henry and Karen through the backroom of The Copa, in which the amera work is so increddible you almost feel like you're following them. Those scenes have some of the best cinematography in film history.
-He always draws the best performances out of his actors. Have you ever seen Ray Liotta better than as Henry Hill? Or Joe Pesci as Tommy Devito? Or Sharon Stone as Ginger McKenna? Or Daniel Day Lewis as Bill The Butcher? Or Leo DiCaprio as Billy Costigan? No, you probably haven't. The only exception is the acting powerhouse, that is Robert De Niro, and even when discussing his best roles, it's the Scorsese ones that come up more than any others (Travis Bickle, Jake LaMotta).
-He made the most realistic portrayal of the mob ever,
Goodfellas.
-He's one of the best directors in terms of choosing soundtracks for his movies. Listen to the soundtrack on
Goodfellas, every song fits every scene perfectly (specifically in the "Layla" montage).
So, Scorsese isn't overrated. At all.
