Hm... It's a tie between Pokemon 2000, Pokemon Heroes, and Jirachi Wish Maker. Pokemon 2000 has one of my favorite Pokemon, Lugia, in it, Pokemon Heroes has two of my favorite Pokemon in it, Latios and Latias, and because it has great music, and I like Jirachi Wish Maker because of the music and simply because I liked the whole movie.
