One thing to beware of with this police procedural is that it's 143 minutes and very drawn out. Director Yoshitaro Nomura has a tendency to explain everything, such as the logistics of the cops as they travel around rural parts of Japan, which he does frequently via words on the screen, to the cops re-stating things that we've already seen or figured out. Also, while there is value to understanding just how much leg work goes into solving a crime, there were times I thought it was overdone, or at least, that the "slow burn" payoff better be high.
Mercifully, the beautiful cinematography offsets some of the issues with pace. Nomura often zooms out back from his characters to show not just wonderful scenery, but I think also to give us a sense for how small these lives are in the grand scheme of things. The past has a tendency to be quickly forgotten by the world, as if it were swallowed up in forests humming with loud insects, but not by individuals. No matter how successful someone may become, no matter the number of years that have gone by, the past is always with us, and trauma can come bubbling to the surface in a heartbeat. This is the main payoff to the film, not a surprise twist in the murder mystery itself, which never really has more than one suspect. There is real emotional power in seeing how the past fits together and affects people in the present. Nomura unveils this quite well via flashbacks set not to dialogue, but soaring music, and the result is a feeling of empathy for a callous man who has killed the kindest of persons. It's melodramatic for sure, but enlightened at the same time.
