Had a bad feeling that we'd end on a cliffhanger, but I suppose that's what happened when a network pulls the plug because this easily sets up a fourth season.
While there's sort of a feeling of finality to it, with the intensity of the fights, with the possibility of Sunny coming back, there's obviously more story to tell. With M.K., Pilgrim, and pretty much Tilda all gone, you'd need other characters to step up.
