What TV series have the best intros? What TV series have the worst intros?

I don't know any bad TV intros. My favorites are Burn Notice and Leverage, and I'm unsure if it's nostalgia but my absolute favorite was always Renegade

"He was a cop, and good at his job, but he committed the ultimate sin and testified against other cops gone bad. Cops that tried to kill him, but got the woman he loved instead. Framed for murder, now he prowls the badlands. An outlaw hunting outlaws, a bounty hunter, a renegade."
