Adventures of the Gummi Bears/YMMV


 * Ear Worm: The title theme.
 * Seinfeld Is Unfunny: When the show first premiered in 1985, its animation and writing were praised for being higher in quality than most other shows that existed at the time. But because many other shows with better animation and serialization have since been released over the years, such as DuckTales (and its reboot), Scooby-Doo! Mystery Incorporated, Gravity Falls, and Voltron: Legendary Defender, modern viewers likely won't be able to see why this show was so revolutionary in terms of animation and storytelling, and will likely dismiss it as being just another cartoon from the 80s.
 * Villain Decay: Or rather, ogre decay. Early on in the series, with one exception, the ogres were regularly portrayed as capable of feats of extraordinary strength. Later on though, they needed Gummi Berry juice to do anything beyond the limits of a human. And the weird side effects that the juice initially had on ogres was apparently forgotten.
 * Also, Lady Bane was malevolent and competent in her intial appearance, but later episodes featuring her have her fail just as badly as Igthorn due to Flanderization of her vanity issues.
