Sailor Moon and its reboot, Sailor Moon Crystal, explore some heavy themes like good versus evil and courage in the face of adversity. Sailor Moon celebrates star-crossed lovers, death and rebirth, and the crumbling of a kingdom, but it also has plenty of lighthearted moments. It's a shojo anime, after all, and this genre prioritizes relationships and the characters' internal growth.
