As bad as Population Bomb was, "Numbers Game" was worse, since it involved people. It was another dream, but with Wheeler and Linka having an overly large family that caused humanity to die out. And oh yeah, it was not-so-subtly implied that Wheeler was a sex addict, hence the family. "Numbers Game" may be the only time I've been genuinely angry at TV. Moribito? Fanboi whining. Tim and Eric? My taste vs yours. Telling kids the world would be better off if they were never born? Utterly reprehensible.
In addition, the show was just terribly written. We've all seen the dozens of sentai formula team shows. Now compare it to a random animated color team show, in this case- Ronin Warriors. Both are kids shows, but one is about kids bemoaning a problem and waiting for someone to do something for them while chastising a member of their group solely on ethnic origin. The other is about kids noting a force of freaking Shinto demons turning Japan into a grave and going to beat up demons and humans with their own hands, swords, spears, and other mystical bru-ha-ha. Obviously the latter entertains kids better, but even beyond that. Tell me, which group gives a better message? "You have a problem? Wait for someone to deal with it.". Or "you have a problem, take a proactive approach."
Oh yeah, Captain Planet's design is a third-world knockoff of Captain Atom.
