To this day I still don't quite understand why people say there is "too much action" in this movie. The Avengers had many more action scenes than MoS and they were longer too. The Smallville and Metropolis fight scenes only lasted a few minutes each whereas the battle of New York alone was like 40 min.
I think people's real problem is the intensity of those scenes. They pack much more of an explosive punch than Avengers or Transformers. Also, let's be honest, eventough people don't want to admit it, what Supes did to Zod rubbed everybody the wrong way. People keep saying "no, its not about the neck snap," but truthfully that probably ruined the movie for a lot of fans and critics. If Supes had flown him into the negative zone or soemthing, i guarantee you would not be hearing such extreme vitriol towards the movie.
Its all a part of change. Snyder and Goyer made a very conscious decision to rock the boat and it worked. They could not afford to make a passeable, forgettable superman film, they had to do something bold to get people's attention and get people talking about the Man of Steel and it absolutely worked. I absolutely think in a few years, especially after BvS, people will look much kinder at this film and realize what it was doing.
