Serenity is a follow on from me watching FireFly, Serenity is a bit of a follow on, but watching Firefly is not a requirement.

In the future, a spaceship called Serenity is harboring a passenger with a deadly secret. Six rebels on the run. An assassin in pursuit. When the renegade crew of Serenity agrees to hide a fugitive on their ship, they find themselves in an awesome action-packed battle between the relentless military might of a totalitarian regime who will destroy anything – or anyone – to get the girl back and the bloodthirsty creatures who roam the uncharted areas of space. But, the greatest danger of all may be on their ship.

I fear that the canceling of Firefly may have been a huge mistake; as unlike Buffy I like this one.
