This movie is not realistic either
I have often seen it said on this board that this movie is great because it's realistic.
But it's not realistic.
Just look at the poster, does that look realistic to you, I didn't think so:

That cokehead thug and his boyfriend shooting uzis into the lake in their underwear is not realistic either. Such things never happen in real life. The director must have been living out his homoerotic fantasies or something, but whatever the case may be, he certainly didn't put that in the movie because it was 'realistic.'
