Animals such as bugs and squirrels are killed by being crushed, stomped, cooked, and shot with a crossbow. There is never any detail.
A young boy falls and breaks his leg, a crack is heard but nothing is shown.
A woman has multiple visions of dead people appearing suddenly, there is usually blood surrounding them. On one instance she sees a child with a bird pecking his face and his neck broken.
This movie contains some bloody scenes but it's not as gory as other movies by Alexandre Aja.
