I watched zettai reido twice. Once withough subs and once with subs. Honestly I find this to be one of my favorite mystery dramas. The story of this revolves around the death of one of their colleagues who was shot by a "fearful" woman who we later on find out more about. There is some kind of freshness to the plot and it involves the way humans think and what some people are "pushed" to do when they get the means to obtain something that they want be it money revenge i don't know what else. although the main role was that of izumi's and in the beginning she was clueless about infiltrations and secret investigations, with the help of someone she matured. there were many different premises to the show which involved back stories and secret plots going on behind the scenes. it's not just one case on each episode it's many cases which all link to one person. the acting, was like always outstanding. small expressions, bigger expressions, style, the small habits each person had and the way they spoke. izumi was able to mature as a role from the beginning until the end and in every episode there was progress. it's really rare to find logical character development in dramas and most of the time the actors can't pull it off. here ti was pulled off greatly. with outstanding guests stars too i could not give the acting less than a 10 it would be unfair. the music was adding to the climax of every episode and to the scenes it was not distracting you from the show and what was going on so i gave it a ten for that reason. i would certainly think that rewatching this after a year would most likely make you able to notice things you weren't able to notice the first time. overall i give this a ten. it's a great watch for those who like mysteries and detective dramas. it's definitely something a mature viewer would appreciate.
