Firefly
A slide guitar and a weary blues vocal over a spaceship. Sonny Rhodes sings words the show's creator wrote, and the argument of the whole series — that this is a western that happens to be in orbit — is settled before a line of dialogue is spoken.
Season 1
One sequence for all fourteen episodes, of which the network aired eleven and those out of order. The titles are the one part of the show that reached every broadcast intact.
