Buttocks shown once; no frontal nudity.

Scenes where sex is implied (not shown though); no nudity throughout.

there are murders, stabbing, bludgeoning but most of the moments of murder are not directly shown (for example seeing the swing of a weapon and then seeing the dead person)

There is often a fair amount of gore shown (blood spatters, etc), and "brains" are shown.

words like "ass" and "bitch" are used on occasion

drinking, drugs and smoking are sometimes seen/referred to

It may be unsettling to see someone eating brains.
