It doesn't make any god damned sense. Either Fox is entirely fucking incompetent or else they always wanted the show dead (Joss did say they were never comfortable with FUNDAMENTAL aspects of the series).
I really, really home there's a possibility Dollhouse can continue on another network. It's too good a show. As much as people BAWW about Firefly, it was never more than a fun show. Dollhouse makes me think. It makes ME uncomfortable, and that's damn hard to do.
Damnit. I decided to write a paper on Dollhouse for my English class. Now it's going to be really depressing =(
EDIT: Who wants to take bets on how long it'll take until people start saying, "Gee, Dollhouse was such a great show, why'd it get cancelled?"
