"But where's that light coming from" BITCH IT'S FANTASY WHO CARES
but also I don't give a fuck if it's fantasy or Gritty Reality. light your fuckin scenes properly because film is a visual medium and you're meant to be telling me a story through visual information. I promise you I will not be as irritated by a slightly non-diagetic light source as by being Literally Squinting To Partially Make Out Some Of What's Happening On Screen
