Character arcs were destroyed in my opinion. That was my favourite part about the cartoon series. How characters developed. Sakka was sexist but was humbled and lead to his character arc giving into realizing he wasn't this hero but needed to humble himself before he became the warrior he was. Was a bit influence on his sword mastery. Aang never goofs off, doesn't show his kid size and how he grows more serious as show goes on but still remains true to himself at the end despite all pressures by stripping the fire lord of his powers. Azula is show with faults at the start, as oppose to her slow mental breakdown. Also Aang is never practicing his bending. All in all the show focused on to keep the wrong aspects of what the show brought, not using what really made the show magical. Bummed out again because special effects and costumes etc were amazing. But after M night Shyamalans movie and now this. Can't see someone doing another live action however. At least I will always have the cartoon!!
