Boston Strangler, based on real killings in the early '60s, comes off as a film that's trying hard to remain rivetingly mysterious as opposed to a Zodiac or a Se7en. It has a first act that instantly hooks your investigative interests, and as the cases begin to pile up, there are many leads the film puts forward. Cinematographer Ben Kutchins attributes as a dark, softened glow to the frames, not too distant from the visual style of a David Fincher thriller. But the plot developments in the subsequent acts don't mesh well. You're given many names and faces, and you're expected to look at each one with a specific level of suspicion. Towards the end, I lost interest, just like one of those cops (played by Alessandro Nivola) who worked on one of the cases. It doesn't take much on Keira Knightley's part to slip into the role of Loretta, and I also liked how Matt Ruskin's writing discussed the casual sexism of that era. But that's all there is!
