Morally ambiguous show is all about crime, iffy choices.
Parents need to know that this show isn't intended for kids; its intense, morally ambiguous characters and storylines are a much better fit for mature audiences. The main character starts out as an essentially good person who's driven to extreme negative behavior (manufacturing methamphetamines and more) by depression and desperation; over the course of the show, his good side becomes less and less evident. There's a good bit of swearing (though "f--k" is muted), frequent violence (sometimes extremely graphic), and some sexual content (a woman is shown topless, but her breasts are blurred, etc.).
