You know, as someone who isn't all that fond of Superman, I got exactly what I wanted out of the movie--the Man of Steel being made principally of iron. Scene where someone punches Supes and you can practically hear their fist break? Check. People getting hit by objects that are not traditionally being swung like baseball bats (like a train engine)? Check. Superman headbutting a giant gravity laser? Okay, that wasn't on the list, but it was freaking hilarious.
What I didn't expect, and ended up liking the movie more as a result, was the idea of Superman not being able to use his powers because of how the world would react, and bam, it was there. The idea that his father, an extremely moral man, would suggest to him that yes, it might have been better if he'd let the school bus full of kids drown was incredible to see. Parallel this to Spiderman's recent ingraining of "With great power comes great responsibility", where the answer would have been yes no matter what, here stands Supes with the complex dilemma that just because he can save them all, doesn't mean there won't be enormous repercussions for the act, and that perhaps he shouldn't.
Of course, all of this reached its zenith at the scene with his father and the tornado. Here's Superman about to lose his father, not to a supervillain, but to something he can easily rescue him from, and yet, for the safety of those around him and himself, let alone for the world at large, he doesn't. He listens to his father, and it costs him one of the most important things in his life. That kind of sacrifice was something I wasn't expecting, but there it was. A difficult choice that defined the rest of his life.
Could have done with the instantaneous ass-grab immediately after he broke Zod's neck, though. Here we have this primal rage after a choice you could see he never wanted to make again, this great moment of impotence for the man most capable...and then, not six seconds later, Lois gives him a hug and boom. Superman is cradling her ass. Really could have done without that.
