There's also Steven Universe, but that's more of a niche show than something you'd suggest. Plus the comedic episodes break up the plot episodes too often.

To add to this too: way I've heard it put the earlier episodes are kind of bland and if you want to watched binge it from beginning to end then the word of the wise - or from the people who tried - is that the first couple seasons are just kind of boring. The later seasons are considered much better in terms of writing and quality and I've heard people put it that right about now is where they got their shit together.

Of course the show wouldn't exist if there wasn't a fan-base in the first place. But it probably doesn't get broader appeal until later.
