I really love the complexities of Steven Universe, especially the later episodes. The fact that they don’t just show healthy relationships, but also explore and deal with toxic relationships, abusive parents and partners, PTSD, and healing all in a way that a kid can absorb. They don’t talk down to the kids watching it.
I didn't get into the series until season five (the pink diamond reveal) and mainly due to all the PD fanart on Tumblr. It inspired me to give it a second chance and fell in love with it. It’s funny, the first episodes I caught on TV of Sailor Moon were the Usagi is Princess Serenity reveal and that got me hooked. I think I really dig the big reveal energy!
