When you design a P.I. office, you plan the lighting so when someone comes in, his face is in the dark and you can't see who he is until he is close enough to jump you. Right? If they lighted the rest of the show decently, I might forgive this "dramatic" lapse. For this show it was just idiotic.
Can someone explain the use of the "Cool Boy" song? I remember the song but not the choreography. How did Slaughter know what Castle wanted to do, and when?
