While Door 17 easily fits the category of erotic horror, the easy scare of depicting a sexual assault is avoided. A man visits a peep show and begins to negotiate with the performer about how much he gets to see. Since it’s a Fewdio film, he obviously gets far more than he paid for.
The finale was a nice twist ending with only one reservation. Personally, I would have found the video more disturbing if the supernatural element had been removed. It is, unfortunately, completely believable that people would do this sort of thing to one another and enjoy it.
