Somewhere in the psychoactive realm between “The Little Mermaid,” “Ponyo,” that mermaid subplot from “Beach Blanket Bingo” and the time you accidentally ate a moldy tangerine and saw never-before-seen colors for hours on end, lies a movie called “Lu Over the Wall.” It’s gorgeous, it’s distinctive, it’s quirky, it’s definitely about mermaids, and it might just make you question your sanity.
“Lu Over the Wall” is a new anime feature from Masaaki Yuasa, who is perhaps best known in America as the director of the ultraviolent, ultra-harrowing television series “Devilman: Crybaby.” Although the two projects are vastly different in tone, they share an extemporaneous quality that is both intoxicating and overwhelming.
