YI JIAN’s review published on Letterboxd:
An anime? A film? No, a kidnapping. I was taken by force, dragged against my will into Mima's mind. Trapped inside, I was forced to follow her downward spiral, my mind slowly decaying with hers. Satoshi Kon, you evil bastard. You... genius. Blurring the line between reality and imagination with each cut, always have us guessing what will assault our eyes in the next scene, building up an unsettling amount of tension with such rapid pace. A work like this requires so much patience and precision, but this is not a problem for you, is it, Satoshi-sensei? Oh what a masterpiece! What a masterpiece!
