Visually lush animation. Written and directed by Makoto Shinkai. I wasn't so enthralled that I didn't feel the echoes of American teenage classics Ferris Bueller's Day Off (1986) and Catcher in the Rye (1951). The synthetic mythos was probably mostly of a piece with Japanese lore (like Godzilla (1954)) but the literal doors between realms is a tired trope that doesn't hold up too well in the action sequences.
The plot has the teenage heroine somehow unplugging a god in cat form from a node that prevents earthquakes. She then traverses Japan (how much I do not know) in pursuit of the incoherent animal with a bloke who has been transformed into a chair; the chair put me in mind of Wall-E (2008). Along the way she has a few funny vignettes about Japanese life, which, like the rest of the movie, hint at dangers that we know will not matter. The conclusion is all schmaltzy love like Interstellar (2014). This mother-daughter (and/or self) love stands in stark contrast to the rest of the movie where (as far I could be bothered to remember) nobody is coupled up.
I don't think I've ever met a cat that wouldn't prefer to help destroy (at least parts of) the human realm. The theme of doors that need closing, the ancestor worship, the evocation of the firebombing of Tokyo (? — or Hiroshima or Nagasaki) suggest the auteur is pining for historically insular Japan.
Maya Phillips: leans on Miyazaki's Spirited Away (2001) and Howl's Moving Castle (2004). Brian Tallerico at Roger Ebert's venue: three stars. A Japanese movie that was big in China.
