Like others mentioned, the musical score didn't really stick with me like the other Disney flicks of such nature.
And, unlike the other Disney "Classics" where I always fell in love with a supporting character (animal)....it didn't happen here for me. Which I found suprising and disappointing.
The Little Mermaid - Sebastian
The Lion King - Timone & Pumba
Mulan - the little dragon
Pochahontas - the raccoon
Beauty and the Beast - talking furnitures and cutlery...

etc...
there were none such characters for me in this film. (wait, kinda, the cajun firefly, Ray, but more so because of his own love story with Evangeline, and how that panned out......that was the highlight of the movie for me)
I think my fave character, besides Ray, (and musical score)....was (with) Mama Otis (the good voodoo witch lady).

(sounded like a gospel choir)
I also found it funny that the 'good friend' of Tiana (the white girl) - looked like a human poodle, which I'm sure was the intention.
Other than that, there weren't any smirks from me at their creative double-entendres, which I've found the most alluring watching Disney as an adult. Lacking here, most notably.
Overall, it was cute but not unforgettable. The significance of the movie was more lasting for me, than the movie itself.
