Mobile Suit Gundam 0080: War in the Pocket

Patlabor WXIII the Movie
What they share
Both films are directed by Fumihiko Takayama, and they both carry the slow burn mood tag, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Mobile Suit Gundam 0080: War in the Pocket, the second film will land in a comparable space — through a different lens.
What Patlabor WXIII the Movie is
Shadows lengthen over Tokyo Bay. A detective’s radio crackles, static cutting through Labor sirens. Two men follow scraped-up evidence into a corridor of sealed files. Denial smells like ozone after another cracked casing. The search ends where a file bears Hata’s daughter’s name. A single frame from Takashi Miike’s mid-period anime shelf.
