The good news is that the network still plans to air the remaining episodes of Season 2 during December and January. Ep 13 of this season will serve as the series finale. My hope is that, since Episode 11 is being filmed now, Whedon and company will have time to write plenty of closure into the final ep. I also can't help wondering if the finale will take place during the time period of Epitaph One," in which case it really should be called "Epitaph Two."
There's one more nugget of good news for the Whedonites in the audience: Joss apparently already has his next project nearly lined up, since he expects to announce it before Dollhouse's run ends. And don't forget about Cabin in the Woods.
I agree with many that Dollhouse is not Whedon's most entertaining series, but I do think it may be the most challenging and thought-provoking fiction of TV.
