You see a lot of blood in the movie, and one shot does show two dead characters who are missing some limbs.
The bear attacks and viciously kills a female character in one scene before dragging her body into the woods. The other characters watch as she is slammed against the car window over and over, smearing blood across the window.
Two characters attempt to kill the bear, but both are killed. This happens offscreen, but you see their bodies afterward. It's not particularly bloody, but you see detached limbs.
A character shoots and kills a bear at the beginning of the movie. This is portrayed as a cruel act, as he shoots it multiple times even as it's walking away.
