If you honestly think that's the best part of the film, you don't understand Superman at all. This is far too generous a 'review' for Man of Steel. It has way more flaws than this and it's a shame they aren't covered here. A lot of things were unnecessarily changed to make the film seem more 'realistic' which betrayed the core concept of Superman. If Snyder thinks Superman needs tragedy for his no killing code, he doesn't get the character at all. AND there are ways for Superman to stop Zod without killing him. I never thought I'd be dissatisfied with a community verdict but I guess there's a first for everything.
I have to agree with you and more. I've been a huge Superman fan for thirty years and have almost every issue he appeared in since 1990. When it comes to Superhero movies I am pretty liberal - I understand that some things don't translate well to real imagery and some comic book elements look silly on the screen. I also like alternate versions of superheros as long as they pay homage to the core values of the character. (For example - I loved Smallville.) Man of Steel slaughtered the character. Killing Zod was one. Another was destroying a city in a fight (hundreds if not thousands of people must have died in those buildings.) Allowing his father to die (even when his father told him not to save him) - I can't imagine Superman (or Clark in his youth) ever letting family or friend perish if it was in his power to save them. I also didn't like the way they handled his meeting and friendship with Lois. I don't know why they felt they needed to have her in on his identity right off the bat - I might have accepted it if handled better but just seemed weak to me I also felt Lois was miscast - she didn't feel she played the part 'strong' enough - she came off too 'girlish' to me.
While I was certainly happy to see the Superman logo on the screen again - I was very disappointed in the handling of the character. I hope this is worked out in the sequel.
