Yes there has been. One of my favourites is 'Lion King'. Nala and Simba's love was so awe inspiring from being best friends to soulmates. It didn't inspire me to love someone but to love someone even more without any boundaries.
Well my answer might be different because the movie, isn't really a Disney animation per-say haha, but I love Enchanted.
Purely because it shows you, that in your heart you might dream of your true love and how he/she looks like, but destiny might have someone else for you, who is totally different from what you first imagined. That mystery is what makes me feel that love is brilliant :)
