Guyver's a pretty great series if memory serves. It's one of those great sci-fi universes where there really feels like so little hope for the protagonist and his friends because the baddies have already taken over the world.
Man, I remember seeing the live-action film WAAAAAAAY back with my dad, one of the very few things I remember us actually doing together, but I could never remember what it was called. Thanks, Vice! I feel like I should check this out now.
