If you loved Rodan, try The H-Man
A bridge between a film you've already seen and one most people haven't. The H-Man has roughly 4.3× fewer votes than Rodan — 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
Both films are directed by Ishirō Honda, and they both carry the dread, late night mood tags, and they sit in Horror / Science Fiction territory. If that's the register that drew you to Rodan, the second film will land in a comparable space — through a different lens.
What The H-Man is
Tokyo. Midnight rain. A discarded suit. A drug deal gone wrong unleashes a radioactive slime monster that dissolves mobsters and cops alike. Panic grips the city. A luridly rendered product of Toho's post-Godzilla atomic anxieties.
