Having this sort of control seems to be the only way for something like this to be useful across a wide range of audiences. My wife will watch people being murdered and maimed in the most horrifying of manners, but the second an animal comes to harm she'll get up and walk out of the room (and then blame me for making her watch it). "Violence" doesn't cover her specific use case, so without the ability to narrow that to "animal cruelty", it wouldn't address our own requirements.
