I don’t like serial killer dramas. I also don’t like shows that pair cold male geniuses with spunky heroines so he can give her a brain and she can give him a heart. Plus, prosecutors and cops up against institutional corruption? Been there, done that. And yet, despite its clichéd premise, Forest of Secrets works. It works because it has Jo Seung Woo and Bae Doo Na as the leads and they act their asses off, refusing to be reduced to stereotypes. It works because it’s as much about human relationships as it is about crime, exploring how the social networks we build can both sustain and corrupt us, about how easy it is to excuse the misdeeds of a friend, a colleague, or a family member. It also shows how an outsider can take those networks down, but it never lets you forget the gut-wrenching loneliness of such isolation. And finally, it works because the writer and the director pay attention to details. Without gushing tears, blaring pop songs, or graphic violence they present smart professionals methodically uncovering the truth. The show does drag out the denouement, with more moralizing speeches than I’d prefer. It’s also not a ringing endorsement of the idea that people can change. It is however, a lovely example of how good writing, acting and directing can bring an old genre to vibrant, urgent life.
