EVANGELION: DEATH (TRUE)²
What they share
Both films are directed by Seiji Mizushima, and they sit in Action / Animation / Drama / Science Fiction territory. If that's the register that drew you to Mobile Suit Gundam 00 The Movie: -A Wakening of the Trailblazer-, the second film will land in a comparable space — through a different lens.
What EVANGELION: DEATH (TRUE)² is
You're a quartet of teens piloting bio-mechs in a war for humanity. But the trauma runs deep, and the Angels keep coming. Director Anno remixes the anime into something like a haunted, abstract recap. It lingers, a question mark.
