You can't take the sky from me...

If you haven't had the pleasure of seeing the original Firefly series, you really owe it to yourself to see it. Order the season from Amazon. Rent it from Blockbuster. Sign up for a Netflix account purely so you can see the Firefly series. However you do it, go see the show.

The movie, Serenity, based upon the series is also quite outstanding. While you're at Amazon, Blockbuster, Netflix, or whatever, pick up a copy of that, too. (I would recommend watching the season before the movie. It's not really necessary, but it adds to the movie experience if you already know the characters.)

Then, once you've become addicted, you really should sign up as a supporter for Firefly Season 2.
