Superman with red eyes seems obvious that he has been corrupted in some way, no?
What would be ideal is if in the next scene out of nowhere Oliver Queen fires his kryptonite arrow in Supes leg, and he falls like a sack of potatoes. It was Batmans plan all along, and the audience would be pissed, but it would be an authentic nod to Dark Knight Returns when that gambit failed. Heck they could even use the same actor from Arrow, that show could use a hollywood push.
