Many women are shown wearing swimsuit/lingerie type clothing.

In the intro, a man is shown naked not detailed, many girls are too but you can't see any details.

People sing about violence.

The whole plot is about tons of murders, and these murders are very graphic, gory, and disturbing.

Occasional use of/euphemisms of damn, bullshit, and bastard.

The captions have bullshit, bastard, etc that aren't always said in the show.

Lots of intense scenes throughout the show.
