With that said, its important to keep in mind that this show isn't meant to be compared to BoJack Horseman, but rather an entity of its own. Besides, Hanawalt confirmed they're not in the same universe. (Sorry Mr. Peanutbutter, no crossover episodes here!)
The art direction and the blend of comedic/serious tones are probably the only similar elements to BH. And they're absolutely spectacular on this show. In fact, its clear that Hanawalt had much more creative freedom on this show, considering the increased 'wackiness' of the style synonymous to her original style of anthropomorphism with both flora and fauna -- evident in her self-published books.
Another refreshing element was the pure-feminine aspect of the show, which big and small lifestyle tropes that would be relatable to most women -- a lot of them very intimate. Even the friendship between the two characters is well established and explored, part of the credit goes to the amazing cast.
Despite being a male, I myself could relate to some things the characters go through, and for the others -- I could definitely understand if not relate, which is another testament to the writing and performance.
It took time to get invested into the characters, since the beginning episodes seemed to lack focus and an appropriate balance between style and substance, but it definitely picks up soon. The latter episodes is where the show truly shines.
All in all, this show is definitely worth checking out. It's a binge-worthy show that won't take more than 4 hours to do so. Though the show is promoted as a companion piece to BoJack, we owe it to Hanawalt, the creators and the cast to not callously compare it with the show, since both are unique in their own ways.
