Well I'm 2 months late to the party...but not skuzzifyable quite yet I don't think. (Somehow I doubt this will stop the cool kids who say IN though)
Just borrowed the DVD set from a colleague in the office. (it helps to work with a lot of people roughly the same age as you...

) My friends who are for the most part sci fi nerds like myself all raved about this show for a long time, but I figured I'd wait until I could get a box set somewhere. Anyway... Popped in episode 1 at 6:30 PM when I got home, stopped after episode 7 at 1 AM. This show doesn't suck.
I'm not sure why so many people compare it to BSG, which I have seen in its entirety. Sure, both are character-driven sci fi shows. However from what I have seen so far of Firefly, it is done in a different tone entirely. We are not talking about the end of the human race here folks, we're talking about smugglers parading about the galaxy all Han Solo vs the Empire esque. Good guy with a funny companion + chip on the shoulder wants to make some coin and piss off the suits. BSG's humor was generally put in just to keep things from being morbidly depressing, whereas Firefly resembles the OLD BSG in the light-hearted nature of the approach. I guess the main similarity I can draw so far is that both shows try to tackle "bigger" issues regularly, and both do so with the subtlety of a sledgehammer. Hey, at least they are trying.
Anyway, I'll take a more detailed look at both after I finish Firefly, but for now I am really enjoying it. If you haven't seen the show yet and are even mildly interested in Sci Fi, (or westerns) check it out.
