I took the advice of badmagic and bought Firefly.
(Couldn't find any of the other stuff people recommended)
It's cowboys in space and I love it ! <== (imagine an extremely big exclamationmark there)
Unfortunately I only bought it today, have only had time to see the first disc, 3 left.
Work tomorrow so I have to leave the rest of it, even though I would like to do an all-nighter and see everything immediately.
(Also, Kaylee is teh hot)
Edited to add that the spaceships are silent when they are flying through space. No Whoosh-ing sounds. Thats shiny !
