Okay, I just watched the movie an hour ago... Honestly, even I have to admit it is better than Iron Man 3. The characters development in the film is good, Zack did shows us how Clark made that though decision to kill Zod...that may be the explanation why Superman don't kills. Besides, they did shows us more about his home planet Krypton, and I like how their technology looks like some kind of nanotechnology stuff. Although some very baffling creatures like those Flying dragon. Especially the end action sequence, which is epic! and I LOVE how Zack make those "boom" sound when the Kryptonian punches. The visual is great, the plot is okay, the cast is near perfect, Henry Cavil kills as Superman ( I don't know all how you Supes die hard fans think, but he looks perfect for Superman). I had spotted at 5 easter eggs!:
1. Lexcorp truck when Clark returns home
2. Smallville banner on the water tank (don't know if that count)
3. Wayne Enterprise satellite damaged when Zod and Supes fought in space.
4. Lexcorp tower when the satellite pieces fall back to Earth.
5. Lexcorp truck destroyed when Zod kicked Supes.
The movie structure is a little weird, keep shows us the flashbacks, I think it's cool, very interesting way to tell a back story without making it boring. But I don't think those non-Superman fans would understand (for instance, my mom couldn't understand, so I have to explain to her every 5 mins!). Beyond that, everything seems perfect for me (except they don't have end credit scene, which I hope they at least show us that Batman or Lex is watching over the news or something like that to led up to the sequel).
I don't know how you guys think, I'm a Marvel fan, die hard Iron Man fan....but I'm totally surprised after watching this film. Maybe because I have low expectation over this than Iron Man 3, but I have to agree that Man of Steel is > Iron Man 3....I would give this movie a 8.5/10
