Apparently the American distributors felt that the original cut was too 'slow', and removed a lot of the reaction shots in favour of extra titles explaining exactly who everyone was and what they were thinking; by the time it had been stressed to us three or four times how slow the Germans liked their films to be, I'm afraid I was feeling rather nervous as to whether this was really the version that I wanted to be seeing, given my bad experiences with some other German epics!
But the director's vision was vindicated — it's hard to image what the American cut can have been like, but since it is crystal-clear what is going on in the minds of the various protagonists, all the explanation must seem rather laboured. And fortunately, there was nothing like the 'one-minute close-up, followed by another minute on the other face' that we had been promised... or if there were, at least it didn't seem anything like that long.
Overall I was reminded of 'Carmen' (probably because I had just been watching Preminger's "Carmen Jones") but with a happy ending — happyish, anyway. Instead of killing the girl, he kills her lover; but then she gives herself up to save him, proving that she's really not all bad after all... The film is beautifully shot in the most fully-developed silent tradition, with conscious plays and parallels of images, and effects of lights: the street scenes take place on a gigantic set built expressly for the purpose. But I was never quite confident of the heroine's motivations (making it hard to sympathise) and I did feel that there were some plot ends left unresolved. Good — beautiful — but not I think unqualified great.
