The saying goes that "to everything there is a season", and the fact of the matter is that the season for the Silver Age was the 1960s, and that time is long over.
If the writers hadn't been so adamant over the last decade to revive their childhood, then the story of Superman in the comics wouldn't have become the clusterfuck it has turned in ot.
If the time had come for the Man of Steel era to end, then it should have been replaced with something that reflected the first decade of the 21st Century, which it wasn't, at least not in the comics.
All the potential replacements we have seen for MoS in the comics over the years have been derivative of what came before, from Loeb's direct Silver Age revival, to Waid's Bronze Age/Silver Age/Multimedia blendered revival, to the use of the movie in Up, Up, and Away, Action Comics Annual 10, and Secret Origin. None of those versions can be said to be original or reflective of 2000-2010 in the same way that MoS can be said to be oriignal and reflective of the 1980s.
While the comic book writers have been busy chasing their dreams of reviving a dead age in the four color pages, TV producers like Millar, Gough, and others managed to forge a version of Superman for the 21st Century with the Smallville TV show.
While the comics have been contradicting each other for 10 years with which version of Krypton is valid, or which version of Lex is valid, or which version of Clark is valid, during that same time frame the TV show has managed to tell one cohesive story with a clear beginning, a clear middle, and, what is bound to become, a very clear end.
