The cool kids are also psychotic killers in the trailer for Netflix's The Babysitter 

A lot of kids, particularly kids in movies, know what it’s like to be stuck in your bedroom while your babysitter secretly has a cool party in the other room. That’s how things start in this trailer for Netflix’s The Babysitter, but the cool party quickly goes off the rails when the babysitter brutally murders one of her friends. The tone isn’t quite as horrifying as that implies, as it leans a lot further toward comedy than horror, but there are some teases that things will take a supernatural turn at some point.

The Babysitter—as proudly noted a few times in this trailer—was directed by McG, and it’ll premiere on Netflix on October 13.
