I think that Singer had a very difficult job on his hands, and handeled it about as well as he could have. For one, the movie had the task of not being a franchise reboot, but more of a "Superman 5" film. But if it were to directly continue from the eighties films, then there would be lots of people having trouble getting it, because lots of people who had never seen a Superman film would be watching this. So the charecter had to be reintroduced to the world. But it also had to be a follow up. To me, that seems like a hard job. I think going down the homage route was a good choice. Those scenes from the original movie introduced the world to Superman very well, so if it had to be done again, why not update them? Obviously, it would have been more original and probably more enjoyable to have a totally new movie, with a few little homages here and there, but when you have the job of re-introducing the charecter AND making a follow up, I think they did a very good job. And now with that out of the way, I think the next movie can be totally kick ass, one of the best Superman movies yet, as long as its original.
