Pretty much this. The last 20 minutes or so were enjoyably batshit, but it took way too long to get there. It also made me think that The Witch did the whole ‘watch a family falling apart’ thing better, they even have similar final scenes, as the surviving family member hooks up with a bunch of crazies
On a side note, how is Alex Wolff supposed to be the son of Toni Colette and Gabriel Bryne?!
