I've told Billy if I ever caught him cheating, I wouldn't kill him because I love his children and they need a dad. But I would beat him up. I know where all of his sports injuries are.
Realism is always subjective in film. There's no such thing as cinema verite. The only true cinema verite would be what Andy Warhol did with his film about the Empire State Building - eight hours or so from one angle, and even then it's not really cinema verite, because you aren't actually there.
