Dollhouse is saved thanks in no small part to our efforts as fans.
FOX said the took a good hard look at DVR numbers as well as HULU and Fox On Demand orders. They don't seem to have mentioned iTunes but I'm sure that had an impact as well.
I do wish they'd have gone for more than 13 episodes and moved them to Tuesdays with Fringe (except they moved Fringe to Thursdays...that's another issue altogether, grrrrr). But I'll take Friday night over no night any day.
Good work on us all, I say.
Now come September we need to keep it up. Encourage our friends to buy the DVD that will included the unaired Pilot as well as the infamous 13th episode, "Epitaph:One" Spread the word...
There is a rumor that the 13th ep may be aired after all.
