Gritty, Natural, Realistic Movies of the 1970s

I’m not sure I’d include this in a list of “naturalistic gritty” 1970s movies – it looks far too slick to me, and too contrived.

To me, it stands out as a movie you don’t have to see if you’ve seen the trailer. I swear, they include all the narrative points in the trailer, and even the climactic stunt. Once you’ve seen the trailer, why shell out to see the actual movie?
