Taslim Dornes’s review published on Letterboxd:
Perfect is for a big, huge, and complicated. Blue is for the sadness, madness, and depression.
I could say this is Black Swan in animated version. This really mind blowing that makes you questioning what is real and what is not. Pretty frightening with anime blood style. Nice plot, it's not just about how to be seen and loved by people when we're not be ourself, it's about the depression that came out when we are so.
