**** out of 5
looking backwards, it's easy to see the influence this film had on cinema in general, but I also thought specifically of Shutter Island, whose key plot twist is very similar to this one. The term "Expressionist" is used rightly to describe this film, but it is more so in light of that plot twist, that the central character, who is narrating the tale (do you need to add a spoiler alert to a summary of a 90+ year old movie?) is actually the one who is insane. The scenery throughout the film reflects the psyche of the characters, and the off-kilter look of the entire film turns out to be because the one telling the tale has gone off the deep end. Great early cinematic acheivement, and still pretty creepy film today.
