Season 3 of Bojack Horseman. Maybe Bojack finally got a wake-up call there at the end of episode 11. Maybe not. We'll see, but I expect that to be the one, given that early in the episode, at an Alcoholics Anonymous meeting, one of the members says something to the effect that sometimes you don't choose to change, but are forced to change. The end of that episode...would very much be a 'forced to change' thing.
It occurred to me with season 2. And it's more obvious now. I have no idea what they were intending to do long-term with Diane. It feels like they intentionally turned her into a satire of Lisa Simpson, and I'm not sure how I feel about that. Diane felt like a serious character in season 1. Then while she has some legitimate problems going on in season 2 and season 3, a lot of things happen from that she cannot tone down with her activism. It's not even a matter of being an activist, but that she absolutely refuses to read the room, brings it up unprompted, doesn't stop to consider the fights she can pick and win, and lets it put a damper on her married life.
