Watched it last night. It wasn't what I expected but it was pretty good. Agree on Bautista he's very good in the role. Loved the little girl too.
I must have missed the usual M Knight cameo in the movie I didn't see him?
I don't remember, but here's a spoiler I found online...
Night Shyamalan's cameo in Knock at the Cabin explained. The director of the film does not make his appearance too far into the movie, as we see him just before the first plague is unleashed. After Redmond (Rupert Grint) is killed, Leonard (Bautista) turns on the television to prove that the plague has been unleashed
