Watched an episode of Prodigal Son out of curiosity, which led to watching several episodes.
While most of it is the fairly hum-drum procedural of the week wrapped around the core premise of a profiler whose father was a serial killer, every episode I've caught has pretty much been stolen by the brief moments of Michael Sheen in the supporting role as the serial killer father in prison. He manages to engage both as that chilling manipulative, former high society surgeon revealed as a very controlled psychopath, yet at the same time as a desperate father trying to stay connected with the son he loves.
