Ultraman: The Next
What they share
Both films are directed by Kazuya Konaka, and they sit in Action / Adventure / Family / Science Fiction territory. If that's the register that drew you to Ultraman Tiga & Ultraman Dyna: Warriors of the Star of Light, the second film will land in a comparable space — through a different lens.
What Ultraman: The Next is
Here's a movie that takes its monster fighting very seriously. A pilot plans to retire from the Air Force in order to spend more time with his sick son. But a strange light in the sky may change both their fates. At least somebody put some thought into this one.
