You woke up this morning, Got yourself a gun, Mama always said you’d be The Chosen One.

When John Adams begins acting like a pompous windbag, his wife, Abigail, reproaches him with a single word.

“Ambition,” Abigail warns, when Adams tells her that he will get a lot of attention if he defends British soldiers in the Boston Massacre trial.

“Vanity” is what she says to steer her husband away from what she calls “ostentatious erudition.”

“Casting,” she might have told the producers of this new seven-part HBO mini-series, which begins on Sunday evening with a double episode.

John Adams is the weakest part of “John Adams.”

Based on David McCullough’s biography of Adams, the second president, “John Adams” is certainly worthy and beautifully made, and it has many masterly touches at the edges, especially Laura Linney as Abigail. But Paul Giamatti is the wrong choice for the hero.
