Yes, the girl's 45-year-old-looking head on the side of the road, being eaten by flies and Toni Collette wailing her head off like Lorraine Bracco. Just heartless and gross, man. I'm increasingly used to horror movies shocking you by going ahead and killing the kid, but a focusing on the kid's severed head crosses a line into puke territory for me, sort of like that pregnant woman being stabbed in the fetus in the Red Wedding on GOT.
Collette sawing through her own neck while suspended in the air? Yeah, that just made me think of Castlevania: Symphony Of The Night's gross-out boss Beelzebub (the yellow rotting corpse hanging by chains with its guts out.)
