TheKing0fComedy’s review published on Letterboxd:
Very disappointed. Of course, the animation is impeccable and breathtaking but the story and script felt by far Charlie Kaufman’s weakest. The script was just, well... fine. Any other Charlie Kaufman script could prompt years of discussion. With this, the dialogue was just pretty average. There wasn’t one piece of dialogue that you could quote. There just isn’t enough story for a feature film. I would think it would’ve worked much better as a play, like it was written.
