On Metacritic, the season has a score of 90 out of 100, based on 7 critics. Emily VanDerWerff of Vox wrote that the show had "found its footing beautifully in season two, earning the title of not just the streaming service's best show, but of one of television's best shows". Liz Shannon Miller of IndieWire gave the series a grade of "A−", praising the depth of the show's storyline, the voice cast and the superior comedy in comparison to the first season. Vikram Murthi of The A.V. Club also gave the series an "A−", commenting that "for the most part, it's an entirely unique, funny, and melancholic exploration into the heart and mind of someone struggling to put his life back on track after a series of dark turns".
Chuck Bowen of Slant Magazine awarded the series four-and-a-half stars out of five, commenting that "BoJack Horseman's second season is an even more confident blend of the various tones it experimentally donned last year, as it's simultaneously melancholic, angry, goofy, playful, and often uproariously funny in a distinctively ineffable what-the-fuck fashion". Entertainment Weekly gave the series a B rating, stating it was "one of TV's best meta-skewers of Hollywood".
