I like the article you've shared, though the only thing that makes me raise an eyebrow about it is trying to boat Anna as a real 'role-model' of a character. However, that may also be because at the beginning she's willing to marry some dude she just met, and during the movie even the movie gets realllly creepy with its message by having characters say "hey, don't marry a guy you just met" and then suddenly having an entire cast of characters all of five minutes later give her a musical number of "HEY, MARRY THIS GUY YOU -JUST- MET."
And I guess since then I saw very little character development on her end, especially considering even in the last fifteen minutes she's still willing to kiss the guy she just met just to break her spell =/ People have brought up to me the whole "no dude, she totally developed, she ditched the guy to save her sister" but honestly? I'm convinced that because the whole story was her trying to desperately make a connection and do anything for her sister, you could have had her sacrifice at the beginning of the story and it still would have happened, she'd save her sister out of love regardless of where you put it in the movie.

But that's me. Hilariously on another note, my husband and I made more connection out of seeing a story of a homosexual girl who has to hide who she is (see even: the christian symbols and church where she's terrified of "letting it show") and when it's revealed she's outcast by her whole community because she's different and an "evil" to them, then she comes out of the closet and accepts who she is but won't go back because she knows of the consequences that should await her, but her sister shows tolerance and magically helps everyone see that her differences still make her human and they, too, accept her in the end. xD
