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.
“Though ambition in itself is a vice, it often is also the parent of virtue.”
“Every thing secret degenerates, even the administration of justice; nothing is safe that does not show how it can bear discussion and publicity.”
