They absolutely must find a way to actually show his eyes glowing this time though.
Yooo, this is all I have an opinion on. It always bothered me. The way they describe mako eyes as having this glowing blue ring around them. It creates such a specific image, that I never saw represented. Cloud's eyes never looked especially out of the ordinary to me.
I think maybe CC did the best job, since, with the rather simplified character models, there is a visible darker blue ring around the iris on Zack. It sure as heck doesn't glow, but the fact that it was represented at all made me pretty happy.
