I'm a huge fan of the scriptwriter, Nogi Akiko. Not only does she write really cool and captivating stories, but she also links a lot of the plot development to current societal issues.

Like UNNATURAL, MIU404 takes a social commentary approach to the traditional police procedural / crime dramas. The first few episodes are seemingly disconnected in storyline (ie. each episode has its own crime to solve), but as the story goes on you'll see how the bigger picture connects. There's more at stake than what meets the eye. And the plot and acting all play critical roles in conveying that to the audience.

I particularly enjoyed the lines said by the MIU captain. I think the scriptwriter really made good use of the character to bring out her worldview and her morals/ethics. The amazing storyline aside, MIU404 is essentially Nogi Akiko's letter of complaint about the current police hierarchy, how the Japanese society treats juvenile crimes, as well as the problems with fake news and internet trolling... and I love it.
