Yes, that’s my take. Beatrice was impacted by his work and compared the stuff Bojack made to Ibsens work.

The Ibsen callback in the last episode. Beatrice’s critique of Bojack’s work is often phrased as, It’s no Ibsen. I think in the free churro episode A Doll’s House is mentioned specifically but I can’t remember exactly.

Henrik Ibsen was a Norwegian playwright from the late 1800’s. A Dolls House is about a married woman ‘lacking reasonable opportunities for self fulfillment in a male dominated world’ according to Wiki. It had a pretty controversial ending with the wife leaving her husband and children.

A Dolls House is likely Ibsens most well known play, with Hedda Gabler a close second. If I remember correctly, Hedda Gabler is the play Bojack is working on with the prison theatre. So, call back to his mom’s beloved Ibsen.
