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.

Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Riders

Mega Monster Battle: Ultra Galaxy Legends The Movie
What they share
Both films are directed by Koichi Sakamoto, and they both carry the foreign gem, playful, uplifting mood tags, and they sit in Action / Adventure / Science Fiction territory. If that's the register that drew you to Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Riders, the second film will land in a comparable space — through a different lens.
What Mega Monster Battle: Ultra Galaxy Legends The Movie is
You lead a last surviving team of light-warriors against a galaxy-spanning army of colossi and their traitorous kin. Then a rogue star flares to life, mobilising the frozen giant who shares Belial’s blood. A director once famous for live stunts tracks each frame like a battle-plan, leaving only scorched planets and reborn stars behind.
