Anyone who thinks this is just a rehash of Scorsese's past gangster movies... I mean, I don't know what to say. The tone, themes, and structure are totally different. Yes, DeNiro and Pesci are back, but they are playing very different roles than we've ever seen them play in a Scorsese movie. And now we finally get to see Pacino and Stephen Graham in a Scorsese movie, and they are GREAT. And the way Paquin is used and the presence she brings to that... also great, in fact possibly the most powerful presence in the film as she brings a moral view that cuts like a knife through all the BS.
The coda of this film whittles away the gangster tropes until there is nothing left but the solemn and universal truth of our frailty, of the ways our choices can impact our lives, and the fact that every earthly thing we strive for can't really be counted on when the sun is going down on us. It is an existential elegy that doesn't just make this a worthy entry for Scorsese in his crime movie canon, it makes it a NECESSARY final statement.
I understand if people don't enjoy it, but this is a remarkably different film from Scorsese's other crime movies and honestly I don't think there's another mobster movie out there quite like it. Let it be the swan song for the genre, and an excellent one.
