People ragging on it because of the unlikable girls
Isn't that the point? They are Connecticut brats who know nothing but wealth and opulence. They have nothing better to do than frolic around a mansion in designer clothes and immerse themselves in their smartphones; their parents are plutocrats who have checked out on being parents. I really don't understand that as an argument for disliking the movie.
If anything, the main low point for the film is that it gets repetitive (and some of the girls' acting at times is wonky, but they're young newcomers and do a good job overall so I can't criticize them that much). Besides that though, I thought this movie was visually fantastic and it had a great last act. Lots of giallo-ish references and really cool compositions. Chloe Sevigny and Timothy Hutton are a treat in anything.
It's not a perfect film, but it's one of the weirder and artsier horror offerings I've seen lately. I really feel like if you're going to criticize it, you should have something else to say besides "the girls are annoying." Yeah, they're 12 year old rich bitches. Of course they're annoying.
