Both anime deal with humanity fending off against shape-shifting lifeforms that threaten its survival using mechas. There are quite a few similar themes, both of them have a somewhat convoluted plot, similar imagery, as well as a somewhat similar ending.

Both serve as a conclusion to their respective series that deconstructs the tropes of their main genre. Both are messy, convoluted, and weird in a way that makes the story better or for the worse.
