Yes, although she seems to lose her flaws as she develops and her quirks. I mean, Rapunzel developed but they kept her negative traits and just had her be more mature, wiser, and no longer let Gothel take advantage of her.

She's the only Disney Princess I'd call mean.

And even more importantly the narrative recognizes these flaws, unlike many other DPs.

^What sarhcasm said. So many other princesses get away with doing crazy things while the narrative and other characters never calls them out on it.

Of course! Thats part of her character!

Oh, definitely. She's very impulsive. She said she'd rather die that be like her mother, after all.
Though I like her, and I like that she acknowledges her mistakes.

And it's part of why I love her! She's one of the few princesses who acknowledges her mistakes and really grows because of them.

except for Brenda Chapman, who seemed to try to make her her own Mary Sue character originally.

and also agreed with sarchasm. of all the princesses who screwed up, only Merida gets rightly blamed for her own bad choices. another bad thing about the 90s movies, they never wanted to admit when their princesses (barring Ariel) were in the wrong. though to be fair Tangled is much worse about it.
