In my opinion, it's pretty good, but the fandom is horrible. The fact it was said earlier that kiwi farms is one of the few places you can discuss it, somewhat safely, should tell you something.
The show is very liberal, and despite me disliking all the woke reboots lately, I absolutely love it. It's a good argument on how a show can be "progressive" and still good. Mainly because they are creating something instead of merely hijacking the success of someone else.
Unpopular opinion: I personally like it a lot more than adventure time and how pretentious it became in later seasons. While Adventure time seemed to set up misteries and arc that rarely paid off, or paid until you lost interest, SU's story arc flows a lot better, all the mysteries pay off. And also unlike Adventure time, which had a propensity to introduce secondary characters that you never see again, SU's filler episodes, the ones not about gems, still serve to world build and make the town more believable, and you will totally get to see all the normal people again and even like them.
All in all, I think it's a cute loveable show with a message of love and optimism that is a breath of fresh hair in a seas of edginess nowadays, but it's certainly not for everyone.
