So far I've watched several dramas featuring autistic characters with Savant Syndrome trying to tackle a certain profession in which normally one wouldn't have expected people with severe autistic traits to do. I gotta say that an autistic detective with a Savant Syndrome was something I haven't expected to see. In a way, this was a very interested take in the usual detective genre.

That said, as much as the series tackled with cases that was referred to as 'discarded mountain' or cases that tend to be discarded once it was determined to not be criminal in nature, the series itself tend to not be on the serious side and more comedic at times.
The tone could also be intentional as well since I do note how at times certain scenes somewhat contain a parody of other shows (like the Galileo references) or real life (like how there's the running joke on Sawa being a divorcee, which may be influenced by the fact Kitamura Kazuki had divorced with his wife the same year). The show even in some instances broke the forth wall.

Overall the drama was really fun and quirky. Gotta say that the characters really start to grow on you after a few episodes and that was one of the reason that it felt easy to keep watching the rest of the episodes till the end.
