If you loved Godzilla vs. Megalon, try Godzilla vs. Gigan Rex
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 Takuya Uenishi, and they both carry the 3am cult, foreign gem mood tags, and they sit in Action / Science Fiction territory. If that's the register that drew you to Godzilla vs. Megalon, the second film will land in a comparable space — through a different lens.

What Godzilla vs. Gigan Rex is
You watch as swarms of Gigan descend on earth, ready to tear everything apart. But Godzilla rises to meet them, a titan against many. A final Gigan looms larger than the rest. Director Uenishi sets up a classic monster showdown. The film delivers destruction.
