Easily the weaker of Keita Amemiya's two Kamen Rider films, but J does many things that ZO doesn't. Kamen Rider J skips out on the backstory of its Rider and instead leaves the questions till later opting for the action-first approach. The creature designs are suitably Amemiya with the direction and music as great as they always are, I could have done without the annoying little sidekick as it felt like Amemiya was trying to draw in a younger crowd with it, given the costume design of Zu it feels like the exact opposite, she possesses considerable dommy energy.
