I just saw the movie. It was pretty good but I am a critic by nature, therefore I must comment on certain things:
1) The actress portraiting Lois Lane was pretty good although I would not have chosen her based on look. She is a natural blonde and when I look at her, I just do not buy she is "Lois Lane".
2) Predictable. There are parts in the movie that you just know what will happen next, I hate that in movies. Like the part when Lois and her son go to the hospital to see Superman. You just know the kid will touch him and he will get better. The other big predictable part of the movie is when Lois is writing on his computer at home after knowing Superman is in critical condition. I just knew she was writing an article titled "Why the world needs Superman".
3) Kevin Spacey did a GREAT job portraiting Luthor. He is an amazing actor.
4) The guy portraiting Superman was also very good although I was quiet disappointed to see a Superman with blue color eye contacts. Oh well...we are in 2006, aren't we?
