the only problem for any SR sequel, for those of us who didn't like SR, is that SR's problems weren't just a lack of Action ( more specifically, lack of superpowered hero vs. superpowered villain action ).
Yes, it's true that SR could have used more hero vs. villain action, but the problems are deeper, they are with the Story, the context which Singer has created.
If Singer and co. just think that SR dissappointed many fans solely because it needed more "action", and that they can correct that by delivering more action in the sequel, they would be missing the deeper point.
They would still have to deal with the fact that Superman abandoned Earth/Lois for 5+ years, fathered an illegitimate bastard child ( who is being raised by another man ), a Superman that seems to be an emotional "wimp," etc., etc.
These storyline problems are much harder to correct. And, no amount of high-octane action will be able to cover it up. That would be like using a tiny bandaid to cover a deep shark bite.
But, again, this is just my opinion. For those of you who liked SR, I can understand your excitement about getting a sequel sooner.
I'm just not excited about anything related to SR........
