From the middle of the movie onwards it becomes nonsense.

As a continuation of the first live-action GANTZ film, Perfect Answer at least attempts to carve its own path, offering a slightly more ambitious take on the universe. It builds a more original storyline than its predecessor and adds a bit of intrigue with its divergence from the source material. But even with that, the result is largely underwhelming. The pacing is awkward, the characters remain flat, and the emotional weight that made the anime compelling is mostly absent. While the visuals are competent and the attempt to add new elements is appreciated, nothing here feels memorable or essential. It’s watchable, but forgettable, a movie made for completionists rather than fans looking for something that enhances the GANTZ experience. If you’re a die-hard GANTZ fan who just wants more screen time in this universe, it’s a tolerable curiosity. Otherwise, you’re not missing much.

The fights are good, but it is too long for what it counts, and it is not understood much what they do
