You absolutely should watch princess tutu! Besides that it’s actually shockingly deep/dark, you liked how fluid and beautiful the kyoani stuff was, right? Tutu has glorious animation, you can (and I have!) match up the characters ballet animations exactly to real life performances of the very specific ballets they’re performing in the show, the costumes are all accurate, all the music is classical orchestral music, it’s….good. It’s very good.
