First, Sorry for my English as it's my second language.

I'm a Big Kindaichi fan have watched almost every adaptation of it. So I can claim here with certainity that Season 3 is the weakest of all.

I was reluctant about because of Matsumoto Jun. Idols don't usually do well in acting. Despite all that, he did a decent job.

So Kindaichi case file, as the name suggest is Murder Mystery series, in which a murder happens every week and kindaichi have to solve it. Its easy to understand that the core of this show was Mystery. Kindaichi Manga have lots of great and complicated cases and that was the saving grace for this season. They watered down the cases for the audience which made the case quite easy to solve. Despite being called 3rd season, it's pretty much stand alone and have nothing to do with previous seasons. So I can it can be good as stater for the people who want to try Mystery genre.

As for characterization, they changed or flipped Miyuki's and Kindaichi's character. They turned kindaichi in edgy and introverted guy who loved eating a lot. I liked the change honestly and Jun did well. Actual Kimdaichi was happy go lucky and pervert and that's why I wasn't sure if jun would have potrayed him well. I think that's the reason why they changed his character. As for Miyuki! There was nothing much in her and they just turned her into a annoying loud girl. But I enjoyed the Kenmochi of this version way lot than 1st season and Neo. I can say that about Takato too.

In the Music department, there was nothing new as they reused much of the music of previous season, which I liked. They even added Arashi ED which I can say was okay is.

Overall a onetime watchable series which can be completed in one day.
