Well I just hope they don't change the style very much. D: Charlie Brown has a very distinct and specific animation and style to it, y'know? And I mean its not like The Peanut Gallery hasn't seen some action recently either; they had a new Christmas Special like last year (the one about Linus and how Lucy hid his blanket from him before their Grandmother came home or something).
I was a bit disappointed with the marvel crossover series's that madhouse did, have no idea what to expect from this. While it does indeed sound awesome, I'm trying to figure out where they thought the demand for a charlie brown anime would come from lol.
