The special effects are great and the actor playing the Man of Steel is impressibve but the plot that the movie centers around - a group of former Kryptonites led by Zod who are convicted of crimes there, sentenced to eternal oblviion and then escape and come to Earth to threaten the human race and take the planet for themselves - has been done already in a former Superman movie. I expected originality and imagination in the producers "science fiction take" but it is not here. A big disappointment.
