At what point did you check out?
It started out really strong. Good backstory for everyone, haunted house, spooky pregnancy, mysterious girl ghost at the start smart mouthing the rednecks...
Then the wheels started coming off. The schizophrenic girl who is chowing down on pills probably should have opted out of the ghost hunt and hung out at home with the heavily pregnant lady, who was a remarkably good sport about everyone ditching her at her birthing party. The husband looks like he might secretly be a douche who wants to mount the hippie girl, who for some reason takes a luxurious soak in a stranger's tub. And there's a fascinating back story of childhood hauntings - perhaps the brother and sister are conduits??
Nope. Preggers flips her car on its roof then hops out and goes for a jog, showing zero concern for her zygote. Obligatory black guy keeps scaring the Asian, because of course the minorities need to be a couple. Dropkick husband throws a tantrum because his wife is loyal to her brother. And the hippie, who inexplicably went for a hike in a long skirt and sandals, finally shows common sense and demands to leave. No, never mind, we'll have sex instead.
That to me, was the checkout. I played Scrabble on my phone for the rest of the movie.
