Yep. Steven Universe is the first cartoon to have anime references.

I loved this scene, it reminded me of why the movie theater is still a great place to see movies.

Also I loved all the references in both this scene and the movie posters and such. I noticed one was clearly a 1970s blaxsploitation movie called "Here Comes the Popo!" and another was a Beauty and the Beast spoof that was actually called "All the Feels."
