Season 4 of Transparent picks up in 2nd half, but will this be the end?

Transparent Season 4 does pickup in the 2nd half, as the plot lines focus more on the central character, Maura - which is completely appropriate. She's the one driving this narrative, and the various plot threads about the sexual transgressions and repressions and expressions of everyone else in her family are only of interest, at least to me, insofar as we can see the connection to the unusual but completely credible and sympathetic family dynamic: a father successful in career and by all other external measures but torn apart since youth because he has identified himself as a woman. So among the things we learn in the 2nd half of season 2: there is a history of gender transition in his family (and this plays a role in youngest child Aly's beginning to question her own gender), she has a burgeoning and mature relationship with a man of her age (Donald), she meets her father, whom she thought had died when she was a young child, and has an awkward conversation with him about his desertion of the family and about her sexuality. We get some excellent flashbacks o Maura in the early stages of her marriage, in therapy, trying without success to articulate a distinction between homosexuality and gender identity - the psychoanalytic practice of the day didn't really have the vocabulary for this kind of discussion. To me, this season could successfully call itself the conclusion to the series, as we see pretty much all the lead characters on the verge of breakthrough or change; I suspect, though, that it will continue until it totally runs out of gas. I could do w/ less of the story line on Sarah's (oldest child's) sex addiction and with Josh's torment over his relationship in youth w/ the family babysitter. The visit to Israel, to me, seemed a little stagey - let's all take a trip! - kind of like the cruise that concluded season 3., though I did like the image of Aly alone in the now-deserted West Bank commune farm, her dreams of peace and camaraderie shattered. All told, though, season 4 doesn't measure of to the series at its very best, it's worth watching to stay up to date on these characters and this important topic.
