For the record, literally nothing in Asriel's response had anything true (or funny) in it, and as such, I have deleted it.
A group of three magical warriors known as the Crystal Gems protect the planet from dangers. They're accompanied by Steven, a relatively normal human boy with a handful of magical powers that he doesn't fully understand. Steven is the son of Rose Quartz, the former leader of the Crystal Gems, who died upon giving birth to him. Steven Universe, at its core, is a story about Steven learning how to live up to everyone's expectations of him, and gaining the knowledge that unity is a more powerful tool than violence.
I'd recommend, if only to gain perspective on it. Not everyone enjoys the show, though its difficult to tell how much of that is due to the toxic fanbase. The episodes are only about 10 minutes long making it easy to binge, but the first 10 or so episodes are notably different in tone (and also terrible). The first 20 are so could be considered filler, though personally I feel that it's still enjoyable.
