Thanapat Poonsapya’s review published on Letterboxd:
As wild, absurd, rapturous, colorful, messy, unpredictable, and confusing as life can be.
From now on, if I'm ever going to be asked to show anything that best encapsulates the maximum potential of animation, FLCL will definitely be one of the first things I show them. There is no doubt that this is one of the most free-spirited shows I've ever seen, the whole thing is basically creativity to the max, a playground where its creators can do whatever they want without any restrictions, and it's AWESOME! Trust me, if there's ever something like a French New Wave for anime, this would perfectly fit that category.
And by the way, every song in this is so FIREEEED-UP!!!
