Unstoppable Horde of Reavers vs. Immovable Psychic Warrior

Awesome show I've become a fan of recently, called Firefly.  Kinda a space-steampunk-cowboy-swashbuckling-pirate-rebel bundle of awesomeness.  It's only fourteen episodes long, ending with the fifteenth segment as a full-length movie titled Serenity.  The pro's and cons are that it has a decisive ending, but the story is over rather quick.  Quite funny, with a good bit of action, drama, and intrigue to balance things out.  

The story is set in the future, where the Earth's resources have been used up, forcing the Human race offworld.  We discovered a new Solar System, with dozens of planets, and hundreds of moons.  They terraformed most of these worlds, and spread across the whole system.  The central planets, those with the most sophisticated technologies, formed a systemwide Alliance, and warred to bring everyone under their rule.  A few governments and militias disagreed, and fought to remain independent.  They were inevitably crushed.  The series starts approximately six years later, following a former militia sergeant, now the captain of a Firefly class transport christened Serenity.  He picks up a rather ragtag group of misfits for a crew, and runs jobs for people needing a ship.  He doesn't much care about the nature of the work, as long as it pays well, and doesn't overly endanger his crew.

And that's just the intro they play before the theme song.

As for the title of this post, you'll have to either watch the show, or look it up on Wikipedia and read the ending.  I'm not gonna post any spoilers.  Ha ha ha.......
