Steven Universe and the Female Perspective

There's something weird about that show. I think I was expecting it to be like Adventure Time, which it kind of is, but there's something else about it that's very unlike most of the cartoons I've watched.

I've decided that the difference is that it's very feminine. I'm not saying that because most of the main characters are female (or gender-less aliens who all look female) or because the show's color palette  contains a surplus of pink. I'm saying that because the show's themes seem to have sort of a feminized bent.

The best way I know to describe it is to say that I'm used to shows that focus on friendship, but Steven Universe seems to focus on love. I don't mean romantic love, at least not exclusively. I mean all kinds of love. Familiar love. Brotherly love. (Though "sisterly love" might be more appropriate given the cast lineup.) It's only subtlety different from other shows, but it's enough to make Steven seem deeply sentimental. Here's one instance that shows what I mean: the Gems go on a mission, leaving Steven behind, and Garnet, usually stoic, randomly stops to tell Steven she loves him. This adds nothing to the plot. It's tender/cute moments like that that I don't think a man would write, or at least most of us don't. But Rebecca Sugar does it all the time.

So I'm wondering, is this the kind of thing we'd see more of if there were more shows created and run by women? In any case, I want to see more of those. As a dude, I really appreciate the atypical themes Ms. Sugar chooses to portay. I want to see what other perspectives our entertainment has been under representing. Steven Universe is kind of weird to me, but it also has a unique appeal.
