The film looks grittier, meaner and tougher than 2006's Superman Returns, the film is taking a very different approach than that of the classic Christopher Reeve films, unlike the 2006 effort.
This could be good news, but then the trailers for Superman Returns looked good and that was utter rubbish so maybe we'll reserve judgement until release date which is 14th June 2013, until then enjoy the trailer.
