NausicaƤ, just for the beautiful masterpiece it is (especially with the whole universe, especially the paper version). Probably the only story that made me feel high for at least one week.
Then, a lot of others Ghiblis (including Grave of the Fireflies, that was so unsanely good, for those that have not seen it, you will just have to watch it to understand, but do not do that if you are already depressed). In the Tim Burton style, maybe Coraline, even if it was not very original, it was a well done animated movie. And a lot of Pixars, of course, especially Wall-E. On the Disney side, my favorite is probably the Beauty and the Beast. Oh, and I almost forgot : Le Roi et l'Oiseau (The King and the Mocking Bird), of course, for being one of these beautiful classics that are sadly not so well known.
