I need to catch up, but I LOVE this show. It's a shame that so many people think cartoons these days are bad and have no substance. Steven Universe, along with the ones that Tulips mentioned, are all exceptionally amazing shows for everyone even if they appear childish on the surface.
But yeah, Star vs the Forces of Evil is so good! I'm going to try and get my husband into it. I don't mind restarting from the beginning, haha.
