If you loved Gantz, Au commencement, try Gantz : Révolution
Un pont entre un film que tu as déjà vu et un que peu de gens ont croisé. Voici ce qu'ils partagent, et ce que le second fait que le premier ne fait pas.
Ce qu'ils partagent
Both films are directed by Shinsuke Sato, and they sit in Action / Horror / Science Fiction territory. If that's the register that drew you to Gantz, Au commencement, the second film will land in a comparable space — through a different lens.
What Gantz : Révolution is
Tokyo. A humid summer night. Splatter of blood. The black sphere demands more lives, but one fighter refuses, another craves the power, and still more aliens arrive. Sato's sequel ratchets up the manga-violence.
