That's me again, sorry. You see, I am French and still traumatized by the 2015 Bataclan killings in Paris. Massive killings during which many many people died and for which the criminal mastermind Salam Abdeslam is still in jail, refusing to talk and even asking for a rowing machine, to exercise. I don't lie. He should see this movie. That's for him. If he was in prison in Russia or Japan, I can assure you he would talk, even sing !!! ha ha ha. So, if you are a terrorist about to commit a massive killing in Japan, don't miss your suicide. This very very disturbing movie is a kind of Japanese L'AVEU. Remember Costa Gavras's masterpiece, back from 1968? The main difference is there you can hardly feel empathy for the tortured.
