"Okay." With just two syllables, the final moment of BoJack Horseman's second season suggested that the alcoholic anthropomorphic horse was on the mend, that things could — would — get better. In front of a swath of bright green grass, looking up towards the sky, BoJack had his epiphany. Season three, which dropped on Netflix on Friday, begins in darkness, with BoJack intoning, "It's a dream come true." And for a precious, fugacious moment, you almost believe him.
