This is a weird kind of drama that's supposed to be watched as a comedy, because it's hilarious, and not as a serious one, because it has too many flaws. The story of each episode gets kind of repetitive. The style is exactly the same one for each episode and you just have to get used to it. Every episode's story is simple, full of plot holes (which is really bad for a detective series) and predictable. Some episodes were mediocre and some others were somehow good. Nothing much to say, except that the last episode is really something. The acting was good. Nagase's role was hilarious and the general cast was funny although the characters weren't really interesting. The music was really good. The soundtrack and the insert song were really good and fitting. Didn't like the ending too much though. If you're looking for something really light, where you don't need to think about anything, just sit there, watch and laugh, then I definitely recommend you this one.
