What they share
Theysit in Action / Fantasy / Horror territory. If that's the register that drew you to Ghost Killer, the second film will land in a comparable space — through a different lens.
What BEM: BECOME HUMAN is
Bay Area dusk. Church bells. A briefcase. Amnesiac Bem lives a sanitized life as a happy suburban husband. But uncanny dreams haunt him. Nightmarish visions of his monster past versus the bland now. A stylish neo-noir anime for fans of dark reinvention.
