I really enjoyed the back-story, it was what made it for me. I didn't miss all of the campy humor of the 80's Superman's. It excluded "awkward nerd" Clark, Jimmy Olsen, no phone booth changes, and bad one liners. I liked that this one laid out why he had his given powers, not just that "He's superhuman, let your mind conclude how".
The fight scenes with Zod were over the top, and I enjoyed that but couldn't help but think that they were pandering to short attention spans but it worked well. Kinda felt like those old school Godzilla films where Tokyo was being destroyed when Godzilla went on a rampage. Too bad Russel Crowe wasn't in the film much although his "ghost" does make a return and Kevin Costner made a good Papa Kent. Overall I give a 4 out of 5 and I would see it again.
Man of Steel is doing good box office business we will probably get that much rumoured Justice League film.
