If people use this term for "Bring Me the Head of Alfredo Garcia" then I'd say you could use it for this film as well.
Hey I never said it was a western . . .
Is it even necessary to do so? Call it a crime film and let it go at that.
Makes none to me either. I'm just pointing out that your use of "I'd say" is an endorsement of what "they say." If that isn't what you meant, fine. But that's what you said.
