In the movie they focused on her problem to try and control her powers instead of knowing her better.So it's nice that Elsa personality was fleshed out more in Frozen Fever.

^^

I don't agree with the others. I think to a degree Rapunzel is mentally strong but mostly she has a lot of issues (and of course being a Disney movie they'll dismissed or glossed over). Merida is basically nice but I wouldn't say she has a BIG heart. Tiana has some charisma, she's just never Rapunzel-level charismatic because she's so serious. Anna's design isn't really any more simple than Rapunzel's or Elsa's. In fact next to those probably more so because Rapunzel just has a generic DP design (pastel dress, long brushable hair for a doll, Ariel/Belle-like face) and we have plenty of magical white-haired girls in striking outfits around (Amalthea, Daenaerys, Jadis, Kida, Queen Serenity, etc.)

all except the Tiana and Anna ones.

Yeah.

Absolutely NOT Tiana

yeah. and also rapunzel and tiana
