If you are unfamiliar with the 'Firefly' series, it is definitely worth your time/money.
Witty dialogue and interesting characters combined with a space/cowboy/new frontier-flavor make for interesting viewing. Don't forget there was also the movie 'Serenity' with the same cast...
Seconded on Firefly, definitely worth your time. Serenity on the other hand is quite different from the series, still enjoyable though.
