An excellent pairing of Keira Knightley and Carrie Coon.

The movie’s “Zodiac” running on fewer cylinders, with many pointed things to say about the difficulties faced by working women in the early 1960s but a lugubrious narrative structure that sprawls and wanders and eventually sputters out.

The matchup of Keira Knightly and Carrie Coon punches up this involving, period-rich but somewhat ordinary thriller that celebrates old-school journalism.

You may be better off checking out some documentaries about the Boston Strangler.
