The little boy is seen naked in a communal bath

Lots and lots of gushing and spraying hyper red blood. It doesn't look realistic, but there is a lot of it. Usually pouring from holes in shirts, but multiple limbs and heads are cutoff and seen lying around. You sometimes see the stump or headless corpse. The most graphic of these is a man who commits suicide and blood explodes/gushes from his abdomen (no wound seen).

Swords are seen passing through bodies

Some people are shot (bloodless)

A bunch of attackers have limbs cut off and flail around in anguish.

The fighting is very graphic and potentially frightening with all of the gore that occurs. The little boy is always present, so younger kids might question why he is constantly in danger and witnessing this stuff. The rape scene is not graphic but is psychologically disturbing. A father wishes his child were dead, this may be confusing to kids.
