There's something very special about movies about women committing violence on women. The violence that women are capable of is so much more terrifying than the violence men commit because it's so very personal. VERY personal. Take a look at films like Martyrs, Haute Tension, and Inside and you'll see what it means to do this kind of violence justice.
However, I think I can draw the line on celebrating feminine revenge when it comes to stuff like this.
The story [edited for my amusement] - When two friends open a Halloween fun house on Devil's Night (October 30th for those playing the home game) it is all fun and games until their former sorority sisters begin to arrive. These six sisters are confronted by their past as the night spins out of control. However, that's not what's in the trailer. What's in the trailer? What looks like the entire movie with (blissfully) all of the dialogue and character development taken out. The trailer includes some 'written by a dude' slut shaming, body shaming, the revelation that one of the girls running the house had actually planned to kill all of her former sorority sisters ahead of time, a lot of black lights and running around in the dark, and thankfully, no POV shaky cam.
Oh, and that witty tagline: Revenge is a Bitch.
Adding to the list of "Americanisms" I don't understand. I've never really understood the sorority system or its importance, because it's not a thing where I went to University, so it's not for me to judge what goes on in Beta Lambda Epsilon after dark, but I think I'll be skipping this one.
