I seen the Swan Princess more than once and yeah it some simlarites. And yes the relationship between Tiana & Naveen is simlar to Anastasia and Dimitri. I thought Anastasia was great movie and I just loved the reaction between Anastasia & Dimitri, it was pretty funny but also rommantic. I think Princess and the Frog and Anastasia is better than Swan Princess, but thats my oppion. Anyways there might be simlarites but its different in alot ways too, and there is nothing wrong with that. I see nothing wrong with this movie at all, its an awsome movie and it also happens to be one of my many favorites just like the other Disney movies.
