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 OOO Wonderful: The Shogun and the 21 Core Medals

Tokumei Sentai Go-Busters VS Kaizoku Sentai Gokaiger: The Movie
What they share
Both films are directed by Takayuki Shibasaki, and they both carry the playful, uplifting mood tags, and they sit in Action / Adventure / Science Fiction territory. If that's the register that drew you to Kamen Rider OOO Wonderful: The Shogun and the 21 Core Medals, the second film will land in a comparable space — through a different lens.
What Tokumei Sentai Go-Busters VS Kaizoku Sentai Gokaiger: The Movie is
You're a Go-Buster protecting Earth from Vaglass. The Gokaigers return, now aligned with Zangyack remnants, seeking phantom Ranger Keys. But the pirates' motives are murkier than they appear. Shibasaki's entry in the Super Sentai series makes time travel a central gimmick.
