Epic story that leans on aesthetic vibes more than writing. Lots of extreme violence, intended to satisfy manga fans, like myself. The addition of Toyoo Ashida's writing (Dr Slump) really gave the movie an identity separate from the manga, but one that clashes with the vibe of the world, ultimately detracting from true desolation and brutality of the manga. Feels like a lost Dragonball film at times, and leads into the flashy combat later seen in Z and other 90s hypergore OVAs. The soundtrack's influence on not only video games like Final Fantasy, but also J-Rock through Gackt is another critical lineage under explored.
