Steven Universe

Steven Universe is an American animated television series created by Rebecca Sugar for Cartoon Network.

The Crystal Gems are a team of magical beings who are the self-appointed guardians of the universe. Half-human, half-Gem hero Steven is the "little brother" of the group. The goofball is learning to save the world using the magical powers that come from his bellybutton and he goes on magical adventures with the rest of the Crystal Gems, even though he's not as powerful -- or smart -- as fellow group members Garnet, Amethyst and Pearl. Despite his shortcomings, Steven usually finds a surprising way to save the day.

Steven Universe was heavily judged after the first episode, but as the series went on, it was considered one of, if not, the best show of Cartoon Network by a very wide audience. It has a rating of 8.4 out of 10 on IMDb, with episodes with much higher ratings than the show itself on the same site.
