Hallowed Be Thy Name (2020)

After his Mom gets divorced, she and Devon move in with her mother. Devon isn't happy about moving away from his friends but meets Mick the first day at school. Mick lives across the street and is friends with Skylar who just got dumped by the star football player.

Skylar wants Mick and Devon to go to a cave with her to make a wish. Devon doesn't want to go, but she says her Mom has cancer and thinks this is the only way to save her.  

Later that day at the cave, Skylar has no idea why they are mentioning cancer. She’s forgotten her lie and has to admit she really wanted to wish for her boyfriend back.  Surprisingly they don't kick her ass or never speak to her again. But they do steal an offering from the cave, not realizing a demon will come for them for stealing his stuff. 

They spend the rest of the movie trying to survive and figure out how to stop the demon. The biggest question is why is anyone friends with Skylar? She thinks nothing of being manipulative, lying, being condescending or rude. She insults people when they don't do what she wants. It's inexcusable to lie about someone in your family having cancer so people will go along with  what you want. 

Dialogue that makes one wonder why anyone would be friends with Skylar:

After walking for more than an hour and finding out Skylar has no idea where the cave is -

Mick: If I would have known you did not know where we were going, I'd be at home at this point,

Skylar: God,you're so fucking annoying.

Mick: If we don't find this place in the next fifteen minutes, we're going home.

Skylar: Oh my god. you're getting on my last damn nerve. You're such a diva.

Devon: Skylar was just being Skylar. (after knowing her for one day and excusing all her terrible behavior)
