This is a criminal minds drama, and the male protagonist Fitz is special, he smokes and drinks alcohol, is overweight, gambles, manic, and full of dirty words, but is extremely intelligent. Robbie Coltrane, who plays the male protagonist Fitz, is the actor of "Hagrid" in the "Harry Potter" series. The thorough analysis of the criminal mind in the play is more like the release, reflection and forgiveness of the dark side of human nature, and the procedure for solving the case may be less realistic, but more exciting.
