- Ensemble Dark Horse: Robbie Amell's Max is probably the most popular character of the movie due to his status as Mr. Fanservice as well as being an Affably Evil Axe-Crazy Lovable Jock. He's generally agreed to be both one of the most interesting, entertaining, and original characters.
- Evil Is Sexy: Bee, Allison, and Max are all so attractive that you might be willing to overlook their butchering people. Max in particular is a Walking Shirtless Scene, while Bee is clearly seen as Ms. Fanservice in-universe by Cole, and Allison spends most of her screentime lounging around in her cheerleading uniform.
- Genius Bonus: The first police code that Cole gives the cult, 1053, means "man down."
- Narm: The fact that Allison is sent flying across the room after being shot by a tiny handgun.
- She Really Can Act: While Bella Thorne had given other good performances before this, her Disney star reputation left a lot of viewers skeptical of her acting abilities. Needless to say, they were surprised and impressed by how well she portrayed The Cheerleader of the teen group, citing her as one of the most entertaining characters.
