Again bold and provocative, there is murder, sex, rape, dismemberment, cheating, all for a woman. You see the desires of man printed out on the screen in front of you.
This is part of the horror film genre, showing the natural horrors of man as the real crimes rather than the later form of horror films in the 30's that were more of a goofy thing like Frankenstein employing external horrors rather than the fear of what man himself possesses inside. That supernatural element in the horror film genre was created much later but it all started out of this bold realism that was emerging in the twenties alongside the stylistic developments of german expressionism, makeup, and Hollywood. The horror genre should be noted for coming from a place of true manmade horrors, rape, murder, theft, blackmail that are notable in greed, the wheel, etc… and then being twisted into masks, monsters, and blood. The horror genre would return to these internal fears again in the late 1960's and early 1970's and again have those manmade horror premises twisted into external monsters and masks in the late 1970's and earl 1980s.
It's interesting how cinema's history contorts what starts out as a direct light being shined on the brutal true nature of man into something that can be masked and hidden so the characters don't fully reflect everyone in the audience.
