It's nothing to do with insensitivity for me, or it's lack of moralism, it's just far too long and indulgent and doesn't really tell a story, and thus isn't very interesting past the "HAHAHA, DRUGS, TITS, LOLS! It tries to latch onto a sort of Goodfellas type of story, but even that's hugely unsatisfactory. The whole "it doesn't comment so you can" nonsense doesn't explain why it's 3 cocking hours long, and why that run time is just repeated efforts to show mostly the same things over and over.
I'm being unfair on it because I'm attacking it, and thus always coming at it from a position of negativity (rather than if I was defending it) If you look at the last page I actually gave it a 7 or 8. Of course it's good filmmaking, and great acting, but it's not very good storytelling, or anything else beyond the technical aspects.
I have this problem with a lot of Scorsese stuff though (and I seem to be pretty much the only one.) Loads of it is style over substance. RiP you mentioned Casino for example. Casino isn't very good IMO. It's quite a poor Goodfellas rip off remembered more fondly than it deserves to be.
I think Scorsese is exactly that, a master filmmaker, but I tend to be a bit bored and uninvolved by his films. Even Raging Bull is the overlong story of a not very interesting person presented in the most gloriously stylistic and artful way. Great filmmaking, but meh.
Blood Diamond was a little shite though. Jennifer Connelly especially.
Yeah, the Jennifer Connelly bit was entirely unneeded. We really didn't need a love story between the two pretty white people shoved in there. But still, it's trying to tell a story, not just film a lot of boys own skits.
