It seems everyone and their mother/brother/cousins friend wants Superman to begin with a huge action scene showing his power.I am in the minority but that would be a mistake. If you start off that big, settling back down into the story could prove difficult. Not only that, there is a chance you do not top that with a later battle scene that is of more importance.If there is to be any action to open the movie I think it should be a tease. Maybe someone is getting robbed, he sweeps in a nearly unrecognizable blur and saves them. Then a quick cut to him stopping an attack on somebody, then maybe another quick cut to him stopping a train from going off the tracks or something. A little reveal panning up to his \S/ would be sufficient enough. DO NOT reveal what Superman looks like in the opening though!Giving it all up for a first scene is anti climatic and a waste. I hope they do not do that.
