I just got a copy of Grave of the Fireflies in the mail today. (One of my new Studio Ghibli favorites). Anyways while watching the bonus features Roger Ebert was talking about the movie and said something I really glommed on to that being something to the effect of Art doesn't depend on how it's done, but how it makes you feel. What a great idea to keep in mind while making anything. Oh and you really should pick up or at least watch Grave of the Fireflies it's a beautiful movie!
