I really enjoyed Man of Steel as well. I liked Kevin Costner's role as well and would have liked him to reprise the role in future movies. I liked that he didn't have all the answers.
The level of destruction is similar to the levels of damage we see in the comic books, but my one problem is that we should have seen Superman actually trying to save some of the people or cleaning up at the end.
I really loved the Kryptonian scenes and would almost like to see a World of Krypton movie set in this universe.
