I found the movie interesting. The story had me glued to the screen. Though frankly, I knew who the killer was halfway through. It's usually the case with me. I probably watch too many crime shows. What did keep me watching was Nino's character, whose story was an integral part of the movie.
The cinematography was excellent. Some pictures I was tempted to pause, because it spoke of so much. Silence is always more difficult than dialogue.
The main character is played by Nino. He's a scientist working on the DNA system. I have watched him in other movies, and I always find him very good. He made me forget that it was Nino that I was watching.
The other main character is Detective Reiji Asama (Etsushi Toyokawa), who is tasked with figuring out who committed the murder. While being a prolific actor, I actually haven't seen him in anything, but I'm definitely going to hunt some of his work down now.
Overall, this is an exciting movie. It has many twists and turns, and I didn't even see them all coming! Worth checking out, even if you have to read the subtitles.
