Story wise it was pretty strong until the last episodes, where it started ot add too many stuff and became a bit erratic.

Oguri Shun is far from being my favourite J-drama actor, but it has Kagawa Teruyuki and I will never miss a drama or a movie in which he acts.
As always he brings all his kabuki learnt experience, although in a less obvious way that in Hanzawa Naoki.

My favourite story line was the beef between both scientists and it feels it never went anywhere.

I would say until the middle episode it was really interesting.

The final is too nice for my liking, but I am glad they included some kind of warning for what could happen
