Tekkon Kinkreet, Kaijuu no Kodomo Recommendations
At first glance, these movies might seem quite different, but the feeling of existential confusion, dread, and delight that they both manage to fill me with is hard to ignore. By the end of each one, you will be left pondering your own humanity and existence. I won't spoil the details, but they deal heavily with what it means to live, to be human, and to exist in the world. The art direction is top notch in both, featuring some of the most interesting and dynamic uses of "camera" movement, framing, and character morphing I've ever seen. They aren't afraid to go off-model a bit
Both films are visually impressive and quite artistic, using the medium to its fullest potential to tell stories that are rich in metaphors and symbolism. Furthermore, he dynamics between the characters, namely Sora/Umi and Kuro/Shiro are somewhat similar.
Kaijuu no Kodomo follows the path of Tekkonkinkreet. A simple adventure story, that follows two boys, turns into an abstract and surreal miracle. Character design, music, visuals and atmosphere transform the anime into something experimental but that doesn't affect it in a bad way. These movies are the reason why Studio 4°C is one of the most stylish and unique studios in the industry right now.
