Nooo! It's on my list though. Because Joss Whedon is brilliant and Nathan Fillion <3. Just need to download it... after Dollhouse.
Have you seen Castle? It has Nathan Fillion in it. And in one episode even plays a joke on his previous role as Malcolm Renolds.
You should, it's pretty good. It has David all dark and dreary for a while and Nathan Fillion is in it for like two episodes as a kick ass psychotic Preacher. And if you watch it you have to watch the spin-off series, Angel. Otherwise it can get confusing...
