>>105462825Lots (but not all) of the ideas in the thread are good, but a few that seem like a good idea to me are
>Fixing the dissonance between the start of the series and even the middleIt's not a secret that the series had a bunch of growing pains at least up until ocean gem, and at the very least smoothing out the transition from monster-of-the-week to overarching plot (such as reducing the dissonance between initial gem artifacts and Gempire tech, and having random irrelevant monsters still pop up throughout the series) would do wonders for, at the very least, filling plot holes.
>Have Steven physically grow up over the seriesIt's established pretty early on that his body reflects his emotional state, but despite his emotional growth, he still looks almost identical in
>>105463075 as he does seasons beforehand. A small detail, yeah, but it'd do a lot.
>Integrate the humans into the series betterThere are exceptions, but the majority of the series has a hard divide between down-to-earth townie episodes and fantastic gem adventures. Exploring the differences between humans and gems in more detail, and having (Steven help) them interact in more persistent and complex ways than "they play volleyball together and forgive each other" or "connie is in the gem fight squad now" could help a lot. Similarly, exploring the alternate earth (and its relations with gem stuff) would've been rife with worldbuilding possibilities.
>MOAR FUSIONSFusions are personifications of relationships, so having them be more frequent characters that change over time alongside their components would emphasize one of the most unique traits about the series [/spoiler:lit]and also indoctrinate kids into one of my minor fetishes[/spoiler:lit].
To summarize, I'd just sorta smooth out the series, following roughly the same progression from episodic to overarching but cutting "raw filler" in favor of active exploration of themes like relationships, maturity, different perspectives, and all that tripe.
