I remember Blue Diamond's first reveal during Garnet's flashback and all the cool theories and fanfic about Yellow and Blue Diamond's courts, how they treat their gems, the types of gems they employ, the mystery of white diamond, etc.

And then the show just completely drops all the gem worldbuilding a season later. The magic/mythical element from the first season is gone, they shat the bed expanding on the sci-fi elements, the new gem designs gradually got more basic, and homeworld itself looked like absolute garbage.
