I have to disagree with this, Firefly is not the type of show Netflix should be focusing on. They need shows with low production costs with broad - lowest common denominator appeal. Expensive shows catering to a niche market (which they pretty much already have captured) is not what they're trying to do here.
There's a few ways they can go, sitcoms and short form comedies are going to be much more profitable for them at this point so Better off Ted is a much better fit.
Then there's the Showtime/HBO premium market (which folks are already paying for as a premium service). But even here I think they'd play it safe short term - more Sopranos and True Blood type mass appeal then Boardwalk Empire and The Wire (both are great, but much more focused market).
