If you loved Superman: The Last Son of Krypton, try Batman Beyond: The Movie
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Curt Geda, and they sit in Action / Animation / Science Fiction territory. If that's the register that drew you to Superman: The Last Son of Krypton, the second film will land in a comparable space — through a different lens.
What Batman Beyond: The Movie is
You're a teen in Neo-Gotham who inherits the mantle of Batman. But a figure from the original Batman's past resurfaces. The film blends familiar noir with cyberpunk anxieties.
