I think Kaori in the manga/Crystal is not as interesting as in the 90s anime. In the 90s anime she got a personality, she "dies" and gets revived with a power-up/new costume and she's got feelings for Tomoe, that's why I really felt sorry for her to get "fried" by Mistress 9, especially because it happens in a moment where she's finally happy and shows human feelings.On the other hand I like how we see how she got possessed (great scene in Crystal) and there is something cool about her daimon form, but the fight felt too rushed. But we didn't get to know her anyway because Crystal is rushed in general. At the same time we got her end told in a different way, so it felt fresh.
I am excited for Eternal, because we'll see finally more of the moon kingdom and Queen Serenity. In the 90s anime I really missed her absence after R. She indirectly gets mentioned in SuperS, if I remember well, when Nehellenia tells that she has been banned by the light of the Silver Crystal (used by Queen Serenity).
I really hope, Naoko Takeuchi will add something special to the asteroid senshi. We already have so many sailor senshi/too many characters. I really wonder how old they will look, because in the manga and 90s anime their age is somewhere in between Chibi-Usa's and Usagi's. Since the inner senshi already look so young, I wonder if the asteroid senshi will look like Chibi-Usa, like little children. I hope, in the final designs, the inner senshi and Usagi will look a bit older.
What are your expectations for the Outer senshi designs? Found this illustration of Pluto from R:
Btw: found this really nice Super-S illustration that kind of blends itoh and tadano:
