What is it, to be a cheesy voiceover montage in the last moments of a season finale? Do you have to try to sum up an entire season’s worth of themes using vague doublespeak and an army of cliches? Will you narrate over clips of our heroes looking vaguely sad or frustrated in the vain hope of wringing some pathos out of this big hunk of corn pone? Must you include strange or cryptic teases for future seasons or series? Or can you just speak in platitudes about heroism and strength and hope that somewhere in that stew of hokum you stumble onto some mild profundity?
