The thing about the whole "Films People Miss the Point Of By Rooting for the Villain Protagonist" thing is that I think it often critically leaves out the actual intentions of the filmmaker. I'm not convinced that we weren't supposed to be rooting for Michael Douglas, or the Joker, or Tyler Durden*... I sure as hell don't trust Todd freaking Phillips with that kind of nuance, at a minimum. "Sociopathic White Man" was basically the action hero of the 70's (in case you thought Dirty Harry supposed to be sensible and mild-mannered).
Like, viewed through today's lens, yes, absolutely, all of these men and horrible, privileged, murderous sociopaths, but for some of these films I don't think the problem is "You got the wrong lesson from this movie"; it's more "this movie is just terrible."
*film version only, the book is pretty clear about how it feels
