Story- Just by reading the synopsis of the story one can guess that story highlights the ethics in the medicine field. While I do agree with with whatever the drama is trying to explain to the viewers and how much ethics is important in Science, the execution was a little poor. It is very intriguing for the first two episodes but becomes a little bit boring in the between only to be saved by a very good finale.
Acting- Kamiki Ryunosuke gave a performance of a lifetime. If Suda Masaki gave a performance of his lifetime in 3 nen A gumi, Kamiki gave that Henshin. Henshin is I guess one of the very few dramas that make good use of his acting ability. I liked Nikaido Fumi a lot here too.
Music- I really liked the theme song oyasumi by Yu Takahashi, it has pretty good lyrics. Not a huge fan of the background score though.
Overall- This series had the ability to be a masterpiece but because of the inconsistent execution of the story it kinda failed to become one. Watch it if you are a fan or interested in the performances of Kamiki Ryunosuke or Nikaido Fumi, they both were awesome!
