Kamen Sentai Gorider

I didn't expect the follow-up to the super-fluffy Chou Super Hero Wars to be a moody existential mystery about death. It's thematically coherent, too, bringing in Kamen Rider Ex-Aid's combo of the doctor, who fights death, and the gamer, who returns from death to fight, alongside the Undead from Kamen Rider Blade, and the resurrection-centric identity of our mystery villain. Some mystery elements don't quite come together, and the Goriders themselves are forced in, but overall, it works well.
