SnowboardJunkie’s review published on Letterboxd:
Now that’s taking the tools at your disposal and making the impossible rainbow across the night sky everyone can see. We will look back on this film as a launching point for what feature film animation can and will be, almost as if they just introduced sound to a silent film. Not only making it cool looking, though it is that, but creating a firm narrative that connects with your conscious and emotions while also making the hair raise up on the back of your neck.
If you’ve ever asked your self what it would be like to open your favorite comic and literally have it become a reality right before your eyes this would be how it should look. It’s funny, it’s exciting, it still has that child like heart bringing you back to the floor of your bedroom flipping through the pages. If comic book movies keep pushing the boundaries with this kind of enthusiasm you can kiss the paper issues goodbye. It’s more than just drawings on a page that move and talk. They come alive dancing, fighting and flying like a ballerina and a bulldozer at a ballroom dance. And it's simply breathtaking!
