Shounen Kenya

Movies from the early 80's that trade historical fidelity and basic logic for sheer uniqueness and memorability. Both include stylised depictions of nuclear disasters, unintentionally funny lines of dialogue and absurd character moments. Hadashi no Gen has some really hard-hitting emotional moments, while Shounen Kenya is just crazy 24/7 and utilizes many "avant-garde" animation techniques to complement that. 

Both have interesting art styles and hurt to look at near the end due to weapons of mass destruction. 

They're both fucking crazy, and awesome because of it. They also both have weird ass art styles.
