Even an amazing show like Bojack can have batches of lesser episodes. This is one of them. What we get amounts to an okay filler episode. Not too far in, it gets side-tracked by an irrelevant murder mystery plot? Nobody asked for this, and nobody wanted it. And the B-Plot sucks. They waste an entire day because of a mistake Mr. Peanutbutter made. It's there so characters besides Diane/Bojack can do something and to remind us they still exist. We get it, show. Besides the first S3 episode, not a lot has been dealing with how Bojack will move forward after his New Mexico slip up. Just showing us the latest things he's up to. But as you can probably see, the rating trends upwards severely for the next episode. So things will get better. Just a writer's block streak. All writers get them.
