It was so blatantly obvious whodunnit that I went on watching two whole episodes, just because I could not believe there's absolutely no twist at all. Also, I couldn't believe anything like this can be promoted to me by Netflix. I feel like a sucker now. Blue balls feel better than this afterwards.
If you find Discovery CI intriguing, this one's for you. Others stay away.
