To keep costs down he's using a couple of film students who want to make "a good dirty movie" for the camera work and has hired the summer house on a farm belonging to an elderly couple without telling them what they intend to get up to.
No good will come of this.
CW: some porn movie imagery, moderate gore
Against a backdrop of omnipresent prudish televangelism Ti West does a sex themed slasher movie.
The early section plays on tensions between the filmmakers in a fairly predictable way alongside some slightly creepy interactions with the farmer and his wife. Then once it gets dark it gets bloody.
I'm not totally sure what to make of it. It's mildly exploitative but also portrays the porn performers as decent people. There's a clear intent to theme it on the fleeting power of beauty and sexual potence but it's very heavy handed.
Once the bloodletting starts you have to suspend disbelief quite a bit but that section works as well. It does suffer from being very dimly lit and my projector setup, which sucks at dark scenes, made it hard to see what's going on.
It kept me watching but I think my general disinterest in slasher movies means I came away a bit unfulfilled by it. 6/10 but if you like this genre it will probably do better for you.
