But not worth paying for. Books are worth it. You can't find that kind of entertainment for free (legally). This, compared to the millions of great FREE podcasts out there, is overpriced.
I would pay money to see such a panel in person, some of the most influential names in animation talking about their origins, comparing and contrasting such diverse fare as Aqua Teens, The Incredibles and South Park. Despite being a few years old (before the ATHF movie, and I would enjoy some discussion of 12 Oz. Mouse) this is really informative for the fan and inspirational for any wanna-be animators out there. Sound quality is 8/10 and about 15 minutes are spent on clips played at the event which do little service to the listener, but worth checking out.
