Whew. That was a durn good action sequence. My only issue... is rather silly. I don't think that Lois would have enough of the right kind of energy to allow Superman to fly. At least without killing her. Because... how many Joules would it take to propel that kind of motion?

However, when he took energy from the earth I was like.. WAUGH DKR Supes!!!1!!111!!!

And of course, his leeching of energy from sources other than solar brings up some interesting questions. Does Superman operate through some method other than photosynthesis? Is he able to leech from all living being? Does he on a regular basis? Waugh! *geeks out*
