Something confuses me, on another board here on ign that has to do with the Avatar sequels, most of the negative comments are to the effect of, "Sure the CGI was amazing, but it takes more than that to make a good movie, you need a good story too." But then you come to this board, where all we have is the previous knowledge that the plot will center around an origin story and nothing else but some brief low quality video, and most haters are saying that poor CGI will ruin this movie. Soooooooo, amazing CGI wasn't enough to redeem one movie, but poor CGI would be enough to ruin another one? Make up your mind people. I swear, fanboys are the most fickle creatures on planet earth.
Now that that's out of my system for a bit, about his suit, a lot people are commenting on the green aura it seems to emit saying it's somewhat off-putting. But in some parts of the clips, such as 10 and 12 seconds, his suit looks noticeably dimmer, which leads me to believe that the brightness of his suit might be related to the charge in his ring. The brighter the suit, the higher the charge in his ring and vice versa. Mind you this is just speculation, but from a storytelling perspective, it would make sense because it would give the audience a visual means of telling how much power he has left. I could be wrong but it seems like a good guess, only time will tell.
