History YMMV / ChoujinkiMetalder

* TooBleakStoppedCaring: One of the reasons the show was cut short was because younger fans were not fond of the rather dark and depressing tone of the series (or able to follow the drama-over-action writing), even for the franchise; the show is easily the darkest ''Series/MetalHeroes'' entry. It picked up [[PeripheryDemographic older viewers]] well enough.
* VindicatedByHistory: This was the most poorly received of all the ''Series/MetalHeroes'' series at the time of its original airing, especially with children. Nowadays, in both Japan and the West, the series is now regarded by many as the best ''Metal Hero'' show due to its darker themes and plot elements.

* CompleteMonster: [[BigBad God Neros]], also known as Gozo Kirihara and formerly Kunio Muraki, is a truly vile EvilOverlord bent on imposing his twisted will on the world. Originally dismissed from the Metalder project and allowed to be imprisoned in Singapore, he escaped thanks to bribery and changed his face via plastic surgery, building up an empire using stolen mob funds, which masqueraded as a legitimate charity. In order to TakeOverTheWorld, Neros focused on mass starvation imposed on whole nations, along with the [[KillAllHumans genocide of humanity]]; Neros even murdered his former partner Dr. Koga, who had protested against using Metalder for evil purposes. After Shingo Ōgi discovers his secret identity, he brainwashes the man to kill Metalder. When this fails, he plans to blow up his own lair, with most of his minions inside, while he escapes disguised as his lieutenant. When this succeeded, he murdered Metalder's ally Topgunder to torment Ryusei. Having no limits to depravity, Neros tried to force Metalder to do evil, and [[MindRape mentally tortured]] him before trying to finish him off.

* ItsTheSameNowItSucks: At the time, one of the reasons ''Metalder'' didn't do well was because it was a huge departure from the aesthetic of the previous ''Metal Hero'' shows. Ironically, many of the concepts ''Metalder'' introduced would become commonplace for later ''Metal Hero'' series such as the lead being a robot and a focus on Earth-based criminals and villains as opposed to aliens.
