Some critics have faulted as “too good” the new Aaron Sorkin film aired on Netflix after a short theater run. To be sure, it can be considered slick. It’s about the trial of the leaders of the unrest in Chicago during the August 1968 Democratic Party’s convention in Chicago by yippies, hippies, Black Panther and generally unkempt many thousands gathered in Chicago’s Lincoln Park. “Chicago 7” may be “too good” but it is mainly stunningly watchable.
