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.
I hold with the old-fashioned criticism that Browning is not really a poet, that he has all the gifts but the one needful and the pearls without the string; rather one should say raw nuggets and rough diamonds.
