Many intense brutal battle scenes, some which involve blood, highly dangerous weapons.
A family is slaughtered offscreen, but you see blood spray on a wall and the bloodied corpses being dragged off by wolves.
The body count is well over a hundred, possibly upwards of 200-300+.
There are a few emotional deaths.
Dead bloodied children are shown onscreen, as well as countless other corpses.
Definitely Very Violent for a PG-13 Film
NOTE: The extended (unrated) version is a bit more graphic/bloody than the theatrical version.
