Proxima Centauri - Good Omens
21 parts Ongoing 'JUST THINK OF IT AS LEAVING EARLY TO AVOID THE RUSH.'
In which an angel, a demon, and their adoptive daughter decide to stop Armageddon. Except it's days away, they've lost the antichrist, Heaven and Hell are both breathing down their necks, and the threat of six thousand years worth of history ending in fire and flames is really causing them to feel the pressure. Any reasonable person would declare success impossible... Good thing this family has never once been reasonable.
It will take all the power (and luck) a pair of eccentric supernatural entities can muster, but together, with a dash of pure human free-will, plus copious amounts of Queen's music, they might just come out victorious.
