Besides good graphics and added scenarios they needed to keep the emotion buildup just like the original series and focus more on the message. Especially When he's in the Avatar state. Katara is the one to show care and love and leadership and great ideas. But they changed her character and took things away from her.
They need to come back to the roots. Only true fans will notice the big difference. Please fix the intro it lacks emotion and add ( But I believe Aang can save the world) in the end. Cmon guys your so close! Make the rest right atleast don't rush. Especially when he's in the Avatar state how he goes in and comes out of it. The messege is really important and the build up to his trigger. Along with other Character flaws, the they created need to be fixed.. just disappointed overall stick to the scriptas much as possible please!
