I'd love to see the explanation for the Superman comic book that Chloe was reading to her son. My theory is that Clark somehow crossed over into our world and found a comic of his own life, then decided to take it back with him. The only issue I'd have with that is letting the kid in on the secret. I mean, how could they possibly know he wouldn't blab that around to all his little school friends?
I also want SV's John Henry Irons. Still pissed we never got him in the series.
1989 - "That Batman movie was pretty good. I wish we had more comic movies..."
2015 - "Aunt May is too young, Aquaman isn't blonde, Apocalypse looks purple, and ALL THESE ACTORS ARE TOO SHORT! HOW COULD THEY DO THIS TO MEEEEE?!?"
