If you're into mobsters/street gangs/bikers, nudity, gratuitous violence, then SOA if for you. First two seasons are insane then it takes on a different trajectory in the third or forth but picks up big time in the new season.
Boardwalk Empire is another good show.
Eh, I'm a little burned out on the dark and serious and violent. I've run through four seasons of Breaking Bad and Walking Dead in just over two months. I'm thinking maybe mad men, but for whatever reason I have a hard time picking it when I look through netflix. Somebody told me to try out Dead like me.
