Is she really that great of a character?
As someone who enjoys the show, but doesn't talk about constantly, I think Peridot is a fine character and has good chemistry with the rest of the cast, and a well done arc (despite it seeming to be a bit too short). But there are better characters on the show, and in media in general. If we're talking the show exclusively, Pearl has more layers. But I don't think Peridot sinks to underrated character status either, since so many people enjoy her. Just my thoughts, but if anyone can help clarify what the appeal of the green gem is, it would be appreciated.
