I just got back from seeing it. I saw it got mixed reviews but I still went in with hopes of liking it and I came away very satisfied, thought it was great. There was one thing that bugged me but everything else was awesome to watch.
I really loved how they went into the origins of Superman, showing Krypton and Superman's real parents. The visuals for all that stuff was awesome. The part that bugged me is when they sentenced Zod to be imprisoned even though Krypton was pretty much doomed, which actually worked to his advantage since the destruction of the planet freed him, why did they even bother?
I chalked it up to the people of Krypton being idiots overall. They didn't do very much right, it seems.
