It's truly wild hearing the claim that Tiana looks so off model that children won't be able to recognize her. First off, she doesn't.
Secondly, that's really such a discredit to Anika Noni Rose whose stellar voice work really brings Tiana to life. I know I might be biased, but I think Anika is truly in the golden trio of princess voice actors with Paige O'Hara and Jodi Benson. To be frank, Tiana wouldn't be Tiana without Anika Noni Rose's inspired acting.
I've been lucky enough to ride Tiana's Bayou Adventure (with all the animatronics working none the less), and found it ridiculous that anyone would claim it was difficult to understand whose ride it is. If you have any clue who Tiana is, you'll know exactly who you're adventuring with.
