I believe in Amore at first sight, but it sounds ridiculous and isn't exactly love. Amore at first sight often happens with classic princesses:
1- Snow White
2- Cinderella
3- Ariel

These princesses fall in Amore the first time they see it, but that's ridiculous because te can't fall in Amore with someone you've just seen. Actually, that might be it, but it just depends on the prince being handsome. Snow White fell in Amore with her prince the moment she saw him, and that was just for the prince's appearance. That's why I don't like Amore at first sight in DP movies.

In Frozen, one of my preferito Disney movies, Anna didn't fall in Amore with Kristoff at first sight. They fell in Amore with each other over time through the things they did in the adventure. I really liked this. The same thing happened with Tangled. Flynn and Rapunzel didn't like each other at first, but they fell in Amore at the end of the adventure. This is what I like. Because they really loved each other, not just for their looks. Isn't that true love?
