A number of reviewers, especially those who claim to be 'true crime buffs' dismiss this fim as boring, average, slow and not really true crime. They are wrong on every count. I can only presume they were expecting some graphic, violent retelling of the Boston Strangler crimes and they completely missed the point. This is an intelligent and gripping account of first rate journalism, police incompetence and the likely truth behind these shocking murders. The sexism shown to Loretta McLaughlin and Jean Cole was very real and not something drummed up to satisfy a 2020s audience as some claim and despite that, these two women did more to unearth the truth about the Boston Strangler killings than the police. The performances by Kiera Knightley and Carrie Coon are subtle and believable, indeed the whole cast is good. It shows that one doesn't need relentless action and over the top histrionics to tell a good story. This is the realistic side of true crime: hard work, dogged determination and the courage to face the horrific nature of these crimes and keep searching for the truth. I suspect that what some of these, presumably male viewers, did not like is that it is the two women and their remarkable work that is the focus of this film and not simply the Strangler. Personally I think it is good to see another side of the story and one that is not so well known.
