I’m glad that I stopped watching Adventure Time - the Rebecca Sugar episodes were some of the best by far, and after she left the quality began to drop. Like The Bird Man, with Xergiok, or Wizards Only, Fools with the arbitrary magic vs science viewpoint held by PB (She has SEEN MAGIC WITH HER OWN EYES BEFORE). And she did the best songs in the show - pretty much every song until early in the 5th season was helped along by her.
I might see about getting into Steven Universe. I’m glad I abandoned ship with Adventure Time.
