And this is the explanation for my bottom 5 princesses: Anna, Tiana, Rapunzel, Elsa, and Aurora (not necessarily in that order)

Anna & Tiana fall under the category of having really irritating personalities at times, and I get very vocal about my issues with them (especially Tiana), but I'd still prefer them over characters like Elsa, Rapunzel, or Aurora who I have no aggravations with but feel like they are archetypes or seriously lack character depth. I feel like that's more unforgivable.
I will give more leeway to Rapunzel, who I feel has SOME touches of personality and at least heart in her and was meant to be more of an archetype to market, and Aurora, who isn't really meant to be a fleshed out character-- but I don't cut slack for Elsa, who's the main catalyst of the film and shows little to sign of personality outside of anxiety/depression. There's no excuse for that- she should have been made better, point blank, within the context of her film.

On the other hand, Anna has personality but the whole jumping from man to man and this demand for romance thing can be very irking but I still like her. Tiana is absolutely fantastic basically until she turns into a frog, then it seems most of her personality centers around her restaurant. She becomes flat. Yes she really wants her restaurant-- but what else. What else interests her? Why exactly does she want to run the restaurant so bad? I feel like that aspect should have been more fleshed out- I would have loved to see more of Tiana's love of food. Some scene where she's describing food and what flavors work better and what don't and her passion for it. But then I spend the second half of the film not liking her much. Because I think she can be very mean. So even though I complain about Tiana more, I'd still take her over the latter 3.
But it does cross lines. I can like Rapunzel more than Tiana at times because Tiana sometimes gets TOO aggravating.

I like Aurora and Cinderella but I do feel they're at a little simplistic- nothing bad with that I do wish a little something more to them.

I like Tiana and Merida, and I think they are complex character (despite Merida initially starting the movie as the uber cliched rebellious princesses). Anna and Ariel are irritating and Elsa is boring, she would be annoying if the movie gave her more focus though.

Belle and Punz are both rather bland. and while I like tiana most of the time, I totally agree. she's very boring during the second half of the movie.

Aurora could be a bit bland but that was because she didn't get as much screen time as Phillip and the fairies did.
I like the other girls too, but I found Merida very irritating and Elsa a bit much.

It's kind of frustrating because I find myself thinking, "You could be so much more!" And I feel all the more like they deserve it because I like them and feel they deserve better.

Neither really annoy me.

It's not a lack of depth for me, per se... Sure, I get irritated when the movie itself lacks depth, and the characters are hastily sketched. But overall, it's a character's actions, along with their personality, that either "makes it" or "breaks it" in terms of whether I feel for them and like them.

I wouldn't really care either way. Ariel happens to have a personality I hate, but has some depth. Aurora on the other hand has a personality I love, but lacks depth, I have Aurora in my top 2 and Ariel is my least favorite... Frollo is an example of a bad personality, but with really good depth. I think there's a difference between a really well done character and one you like. You can still have a strong character, but still let them have an awful appeal. As far as annoyance... If a character was just annoying, but still really fleshed out that would get on my nerves more than a character that was nice, but no real thought was put into it. I don't mind if a character's bland as long as they make it believable and it doesn't butcher the story. As long as enough effort is givin there isn't much to be annoyed about... At least in my opinion.

I don't usually mind characters who are sort of blank slates.

Elsa is more annoying than SW to me. And so do Non-Princesses like Esmeralda and Megara.

I don't mind with bland or lack depth personalities in a DP, that's why I can like the princesses like Aurora and Elsa.
Most of princesses that I don't like have more depth and complexity personalities, like Tiana and Ariel.
