This drama story wise has a main point and that is to solve cold cases that the police hasn't been able to solve and also how that affects the lifes of the people involved in those cold cases. the various cases were rather strange and i was always not really good at finding the criminal, well sometimes. besides that, there is a second part of this story . it revolves around solving a past cold case which has stigmatized two of the protagonists. the plot as it evolves leads to something unexpected.for a crime drama the stories it has are also very heart warming. the acting was superb, like always ueto aya was able to show the maturing of her role gradually. it wasn't something that happened immediately. each episode showed a little growth in her. of course the rest of the veteran actors were lovely too. masayuki was rather funny, the funny relationship of his with sakuragi was at times hilarious. the music of the drama was spot on. it accomodated the feels of the story and everything perfectly. music should enhance a story, not take over it. i think that rewatching zettai reido immediately is a no no but if you want to watch again after a while i think that you won't always remember every detail of each episode so this means you can enjoy it once again. overall i liked this drama more than the usual crime dramas that i have watched, mainly because of the focal points that it has. it doesn't only revolve around solving the crime but also talking to the families of those who died and saving them from the uncertainty of "why" their precious family member died and who did it. the second focal point is character growth which i like it when i see it in dramas and i appreciate it more than characters who show no growth and behave the same and think the same from the beginnning of the drama to the end of it.
