Now this is a film. A chilling and legitimately terrifying look at science and moral. Boris Karloff is famously tragic in an iconic performance, but the rest of the cast is no less great. Colin Clive in particular pores pathos as the mad Doctor. The expressionist photography (a wise choice, given the Easter-European setting) and gothic set-design give the film an unforgettable atmosphere. The art is moody; full of shadows and dark clouds, all seen at erratic angles. This must be how the monster perceives the world. Sure, it’s no Dr. Caligari – it’s something else. An American classic.
