As someone who absolutely loves Heat, I don't really think of it as a "heist movie". It's definitely got some heist stuff in it, but what defines that genre to me is that the whole movie is building up to and executing one big heist. Imo it's more of a cat-and-mouse crime drama, and a fantastic one at that.
For anyone else reading this, if you haven't seen Heat, it's well worth your time for the diner scene alone.
I don't need to follow him to get that result
