Jeon Woochi (2009)

In one scene a fighter kills another fighter's by breaking their neck; we see their head turn at an angle and a cracking sound

In one scene a person cuts their own arm to see a trickle of blood come out, and later their sleeve is wet as more blood drips out

an arrow pierces the head of a creature so that it it is stuck in their head and there is blood around the arrow entry point. shown for maybe 3 seconds total

kung fu violence, sometimes involving swords, arrows, etc. Some occasional mild blood splatter. Monsters bleed green goo, also mild. A character gets stabbed with a tree branch and some green goo drips out.

some social drinking and smoking

the monsters look like intense rats/rabbits. nothing too bad but their ferocity may scare younger kids.
