They raised their son (Max Burkholder) with patience and good cheer after he received a diagnosis of Asperger syndrome, and if meant that their daughter Haddie (Sarah Ramos) occasionally got short shrift, the atmosphere in their house was such that she grew up in a dignified, smart young woman none the less.But my affection for Adam and Kristina began to curdle last season.

And both Kristina and “Parenthood” seemed to decide that Bob was some sort of bad person because he had previously dated Kristina’s niece Amber (Mae Whitman), who might have been younger than him, but was certainly of age.

“Parenthood” treated the mayorality not like a serious job, but like an appropriate reward for Kristina’s fortitude.

This year, Adam and Kristina went ahead and opened a charter school, once again with parenting Max as their main qualification.

The six Braverman families at the heart of “Parenthood,” Jason Katims’s family drama, which is now in its sixth and final season, initially looked like a kind of liberal ideal.

In adorable craftsmen houses and in small apartments, the Bravermans raised interracial families and a boy with Asperger syndrome.

The clan included stay-at-home dads, single moms and corporate-drones-turned-recording-studio heads.

“Parenthood” may have been a sly endorsement of conservative visions of self-reliance and strong families, but it was also overwhelmingly, unrelentingly a reflection of its Berkeley, California setting.

And as “Parenthood,” a show I have loved, draws to a close, that ethos is driving me slowly nuts.

“Parenthood” has become everything that conservatives love to parody about liberal culture: myopic and obsessed with self-actualization to the point of doing real damage to others.

Most of my problems center around Adam (Peter Krause) and Kristina (Monica Potter).

For the first few seasons, they seemed like the most stable leg of the zany Braverman table.
