If you loved Fullmetal Alchemist, try The Relative Worlds
A bridge between a film you've already seen and one most people haven't. The Relative Worlds has roughly 8.9× fewer votes than Fullmetal Alchemist — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theysit in Action / Fantasy / Science Fiction territory. If that's the register that drew you to Fullmetal Alchemist, the second film will land in a comparable space — through a different lens.
What The Relative Worlds is
High school mopes get an inter-dimensional upgrade when a parallel Shin drops into their lives just as they’re about to graduate. Kotori must now babysit two identical boys while Shin recovers from jet lag from a reality hop. The universe waves goodbye by dumping emotional baggage on everyone.
