The only thing wrong with the movie is nothing! It's a fictional movie which doesn't need to be analyzed to death, as if that analysis would alter the movie as it is now or would make a difference anymore. The movie is done, it's out. It was made for the enjoyment of Superman fans, and as a fan, I think it's a great, marvellous, awesome movie! I loved it, and the negative reviewers didn't know what they were talking about or just wanted to look 'intelligent' with what they wrote.
I think it is a timely take on the Superman mythos, I congratulate them for casting Henry, and I think the movie succeeded in re-booting Superman. Henry Cavill is now Superman, as much as Christopher Reeve was Superman during his time. Today is a different time that requires a different vision, and Man Of Steel succeeded in re-invisioning Superman for our time. No movie is perfect, there can always be flaws found in any movie, so to put it under a microscope is a foolish waste of time and design to just ruin the moment for those who loved it. If you enjoyed it, great. If not, sorry about that.
Can't wait for the sequel...
