BOJACK HORSEMAN
Netflix, 3:00 a.m. ET
SEASON PREMIERE: This is the sixth and final season of this improbably entertaining animated series, about the everyday misadventures and problems of a former talking-horse TV star. Will Arnett provides the voice of this equine has-been, and believe it or not, it’s one of Arnett’s best roles. This final go-round is divided into two half-season chunks (the first eight episodes arriving today, and the final eight dropping next January). Bojack – the horse, not the series – starts the season in and out of rehab, which means we get to see him sober for a change. But not for the entire season… Meanwhile, he’s at least doing better than his old, bitter co-star, who’s dying of cancer. But still cracking jokes…
