I saw the “twist” ending coming from a mile away. However, the mystery isn’t the major sticking point but how it expresses itself across the lives of multiple perspectives. The Claw is an individual who has terrorized the city multiple times but he’s a figure who is arguably not responsible for his actions. Superheroes are prone to making more excuses for him than the public which he menaces and we get a nice little reflection of how the former’s treatment of villains like, say, the Joker would come off to the people.
I was a big fan of “everyman perspectives” and the reason they succeed is on the strength of the characterization as well as giving a new perspective to extraordinary events. That is the case in SCPD. I think the city could have been developed a bit more and the superheroes a bit more likable but given the nature of the case, I suspect Keith didn’t want them overshadowing his collection of Muggles in a world of superhumans.
