This is a competent True Crime Show, dealing with six serial killers/murderers across 12 episodes. It's well written and presented with this numbing atmosphere, that has the crimes droning in your head.The reason that I don't give five stars is that I feel like the premise doesn't really go anywhere. It's presented as these two things running in parallel (true crime cases, and insomnia) but for this very limited run show, both plotlines don't really go somewhere and suddenly the show is just over.
