I too, though
Grave of Fireflies was very sad, Tetsuwan Atom. Yet, there are several that contained brutal violence that simply overwhelmed me at the time. 1 is
IN COLD BLOOD. While the violence was off screen, it just freaked me out; I think I saw it in HS. It will seem strange that I totally love the
SAW movies, but these are pure fiction; that one was supposedly based on fact.
It is still inconsistent because am horrified at a few films I know are pure fiction, while most slasher films have me ROFL.

I guess it depends on who is the victim.
