This is what I love about Japanese cinema. It is not all the time that I could catch a story as gripping as this one. I'm a fan of crime mysteries and this one is a treat! I have "Confessions", a Japanese film, in my mind during my first watch of TSWMC. Although it is not as psychological and as dark as the earlier film, there was still the trademark of the wonderful skill of plot construction of its writer. (Both films are based on her novels) I liked this film even more because of the appearances of Mao Inoue and Mitsuki Tanimura, and also because the theme of the use of social network inappropriately at times is timely and significant. Direction was okay, it did not feel forced and I liked it that way. Actors did really well. Not much of violence were shown. You'll like this even more if you're a fan of plot twists in movies. Personally this is the best Japanese film (if not the best film at all) I've seen this year so far.
(Review previously posted on my Letterboxd account.) I recommend this crime mystery/drama.
