I'm well into season one, but I can't comment beyond that. So far, I have been kept guessing at what is going on; every episode seems to reveal so much, and yet there's always another twist. So far, the first three episodes each contained a sex scene(the first was intimate, the next two were graphic), and there was one more in episode 9(I haven't seen beyond that). Language is kept to PG-13 level, but there has been some drug use(snorting cocaine, taking pills, smoking, drinking), and a bloody corpse is seen in nearly every episode. There's little onscreen violence, although we see glimpses of a disturbing struggle, complete with the aftermath showing a knife impaled in the loser's body. One woman was shot, a man was hit with a baseball bat, and another was hit with a car. A man also pulled bloody teeth out of his mouth in a very disturbing manner.
