That's interesting, @gano , and I can understand where your personal perspective enters into it. (As for myself, I cannot stand Yellowstone.) I only have preconceived notions of Boston, but if I had the personal connection that you described, I would not be able to get enough of Black Mass. As it is, I will watch it whenever it's on a movie channel without commercials and unedited. (And not because of Johhny Depp.) I really get a kick out of the interaction with the Halloran character that Sarsgaard portrayed. In the Departed, I remember a scene that I enjoyed where Nicholson came out of the backroom of the bar to talk to DiCaprio and he (Nicholson) was all blood spattered and kind of happy looking. Whatever was happening back there, the viewer knows it was bad but apparently business as per usual. Another scene that I found memorable was the one (I think it was Nicholson and Dicaprio's first meeting) where Nicholson hands DiCaprio a severed hand in a freezer bag to dispose of.
Anyway . . . ramble on. . .
