Just bought the 4 disc series for $28CAN. I saw the movie a while back-loved it and was toying with the idea of getting the series after I think it was Raps who bought it on Boxing day. I never watched the series when it was on TV because I was into Farscape and Stargate-SG1 and two sci-fiers was enough for me, so I never gave Firefly a chance (it's people like me why the series was cancelled). Anyway, now I can't get enough of it.
I highly recommend checking it out or the movie if your looking for something to watch.
