As a a big fan of japanese movies/drama crime,mystery, thriller, I dont find this movie bad nor good, just in the middle. The only thing that shocked me was the age difference. The rest was predictable, the doctors reason was kinda shallow. i dont know. i probaby watched too much crime thriller that this movie just feels normal. I hope i can find a korean movie that would make me wanting more. For now, Japanese crime thriller movies/dramas are still top notch for me.
