Some shows you want a season 2 immediately, Don't call it a mystery is one of those shows. The cast works so hard to sell their roles while maintaining three different tones running simultaneously, an excellent effort.
This is up there as one of my favourite mystery of the week shows. The script is fascinating and it gives the audience a chance to solve things without any red herrings popping up. As long as you pay attention you'll be right there with it. The last episode had a puzzle from illustrations- for all of you learning Japanese - that was pretty fun to solve.
I can't say enough good things about the show, left me teary eyed a few times. 9/10.
Next, Romance Doll.
