I personally liked, Spirited Away, My Neighbor Totoro, Princess Mononoke, Kiki's Delivery Service, Howl's Moving Castle and Grave of Fireflies. I enjoyed all of the movies I listed simply because.... Well... They appealed to me when I was younger... That's all there really is to say about it, without re-watching them I wouldn't really be able to give you a summary on why I liked them
