I can agree if you say this episode is too explanatory. But I can never agree with the point that the show is going downhill from this episode on. This episode successfully loads up the show onto the historical context of the 1960s. It was the era of revolutionary thoughts, women's independence, and the demand for diversity. This episode somehow awakens the Weissman (one Marxist, the other feminist), and involves the estranged Maisel in businesses in exclusively non-white settings (one Black music, the other Chinatown). This change makes me anticipate more dynamics in the future episodes.
