It's an interesting movie with a frightening story, where by the title it may seem that the whole movie will be about Boston Strangler, but in reality, the main focus is on character of Keira Knightley who gave an excellent performance. Many people didn't like the "too dark" style of the film, but as for me, it gave the movie "feelings of fear and cold".
There are some moments that I didn't particularly like: little attention was paid to the relationship between the main character Loretta with her husband, and overall the frames with the family were inserted very chaotically. Also, the ending came out too crumble and confusing. But if you like movies such as Zodiac, Se7en, Prisoners, you should know these movies are certainly better :) But most likely you won't regret the time spent watching Boston Strangler.
