1. The Light Bulb Scene
Great season opener. Set up Bojack's new show, Philbert, Princess Carolyn's plan to adopt a child, and Diane and Mr. Peanutbutter's divorce (in an ending scene that made me scream). There are great moments sprinkled throughout (especially the phone call between Bojack and Hollyhock is adorable), and all of the major characters are given something to do, and interact with each other. The season's show business commentary is off to a great start in this episode. ("If it's driven by character, that means it's not gratuitous!")
2. The Dog Days Are Over
The chronology of this episode is really creative while still being easy to follow. The "listicle" format allows for Diane's commentary and some good humor. As we work our way toward the beginning of the episode (Diane sobbing in her car), there are a few heartbreaking moments. Of course, Diane seeing Mr. Peanutbutter with his new girlfriend, Pickles -- but I was particularly hurt by the Diane/Bojack interactions in this episode. Bojack just wanted to go to the party with Diane :/
3. Planned Obsolescence
I really enjoy the Princess Carolyn/Pickles in this episode dealing with the specter of Diane. Bojack teasing Gina over her love for musical theater is fun. Todd's storyline is... fine. There are some good jokes (look at the foods on the dinner table), but I'm not that into it.
4. Bojack the Feminist
This season's issue episode! A Mel Gibson-type actor is cast in Philbert and Bojack ends up a feminist hero by doing the bare minimum. This show has dealt a lot with the recurring issues of sexual harassment in Hollywood, and this season dives into that later on, but this episode is more about famous men who are known to be horrible in their personal lives, and whose careers barely suffer as a result. There's plenty of irony in this episode upon a rewatch ("don't choke women!"), as it's clear that Philbert plays off of Bojack's problematic persona. The end of the episode really sets things in motion as Diane finds out about New Mexico.
5. The Amelia Earhart Story
I love seeing teenage Princess Carolyn, and I love David Sedaris voicing PC's mom. Inspired. The episode also sets up Bojack's opioid addiction, which is the thrust of the season.
6. Free Churro
This is hands-down the best episode of the season, and one of the best episodes of Bojack ever. Top five for sure. The entire episode (minus a flashback cold open) is a eulogy delivered by Bojack at his mother's funeral. This episode is funny and heartbreaking and unique. Will Arnett Emmy when?!
7. INT. SUB
This episode is creative and funny as a couple share stories about their clients over dinner. But the real headline: Diane. Did. That. What a power move.
8. Mr. Peanutbutter's Boos
I love that Mr. Peanutbutter is finally realizing some things after five seasons. This is a very good and funny episode as it switches between the four timelines. Lots of good era-related jokes.
9. Ancient History
I hate seeing Bojack waste his limited time with Hollyhock trying to get drugs. And Jesus Christ, Bojack, just give her a hug and tell her that you love her. I enjoy seeing Ralph again, and... I just want them to be together :( I love the re-appearance of Meow Meow Fuzzyface. I don't love Todd's subplots in most of the season; he used to be more interesting in seasons 1-3. The ending of this episode made me scream.
10. Head in the Clouds
Character actress Margo Martindale! There's lots of meta introspection in this episode, as Diane ponders whether it's ethical to make a bad character sympathetic, and whether that normalizes bad behavior. ("We're all terrible, therefore we're all okay.") Henry Fondles' innuendos are funny, which makes the subplot sorta worth it. Mr. Peanutbutter and Diane hooking up?! But the headline is: The Bojack/Diane reckoning we've been waiting for. Last season was much more Diane/Mr. Peanutbutter, so I really needed this.
11. The Showstopper
The notorious 11th episode. It sure is something, but it wasn't as cathartic as Time's Arrow or Escape From L.A. to me -- more on par with season one's Downer Ending emotion-wise. I like how it switches back and forth between the show and Bojack's life, and how it's hard to tell what's real and what isn't. The musical number is great and unsettling, and the ending packs a horrible punch, as Gina delivers the one f-word this season. Also, what's up with the stair to heaven imagery? Bojack didn't die this season, but... maybe it won't be much longer.
12. The Stopped Show
The fall-out of last episode, and set up for the next season. Princess Carolyn adopts a baby, Mr. Peanutbutter proposes to Pickles, and Bojack starts rehab. I love that the season ends on Diane. Good for her.
