I am coming to this thread a little late, but I saw this on Sony last night. Easily, I can see it becoming my new favorite show. This is because of Wheadon and not because it is a comic book show. I felt for moments the same joy and willingness to be absorbed in the universe as I used to with Buffy, Angel, and Firefly. There has been something missing from television these last ten years and that was a Wheadon series.
EDIT: And Dollhouse just didn't have that same feel.
