I prefer Tiana, but at first I wasn’t too bothered by the fact that Lottie was the fandom favorite because other bubbly characters like Rapunzel were popular. But then Frozen came out and everyone fell over themselves to praise Elsa and hated Anna because Elsa told her not to marry someone she barely knew, even though Tiana successfully kept Lottie from doing the same and without ever shaming her. I haven’t been able to look at the Disney fandom the same way since.
I’m happy that with Elsa, and now Moana, Disney has been upgrading their princesses to queens. I hope this continues!
