The very start of the movie. When the music "Main titles" is playing. It tears me up. The music, the animation. Both are so beautiful and work so nicely together and makes me feel all warm and fuzzy. I have the soundtrack on my iPod and went I listen to Main titles it reminds me of my childhood and watching The Little Mermaid on video.
I have so many. I love the beginning when they sing fathoms below and the main titles they play in the beginning. I like the part of your world reprise. I like when Ariel is on the side of Eric's ship. I like when Ariel is in the pink dress and they are sitting at the table. I like the tour of the kingdom. I love when Ariel is in the rags and Eric comes over. I love when Ariel gets her voice taken away. I love when Vanessa sings that song in front of the mirror. I love when Ariel gets her voice back. I love the ending where King Triton gives Ariel legs and the sparkley dress, and when Ariel and Eric get married. I love the whole movie. :) :) :)
I love this movie to bits. But saying that...the best part is when Ariel and Triton hug after the wedding. That moment always makes me tear up. And then the gorgeous choral anthem ending with, "Now we can walk..now we can run...now we can stay all day in the sun..." After all this time, that chorus, and the beautiful visuals, still makes my heart lighter inside.
