I'll start off by saying I am not a fan of the character design, I guess I prefer the the previous style over the new. That's not to say it's terrible I don't hate it I'm just not a fan. I'll get used to it eventually I guess.
I am also not a fan of the CG Showdowns, I would have rather had them be traditional animation.
As I said before I prefer the old, but I can't expect miracles. I would have love for Tom Kenny to voice Raimundo again or Grey Delisle to return as Kimiko but the voices are ok. Ex. I instantly recognized Cree Summers as Wuya.
I am just glad to see a sequel even happen, it always seemed impossible. All n' all I can't wait to see what's in store.
