Stars and S are the only seasons I can watch every episode and not be bored with the fillers. I love the manga final battle but I love how they made the anime battle be it's own. It was perfect. Only thing I hate about the manga version is what the heck happens to the Starlights!? If we get that far with the reboot, I hope they switch things up a bit with that.
And I always get choked up with Michiru and Haruka's death. It's so sad yet beautiful. And the emotions from Usagi's screams are just too much. It's so heartbreaking.
