That's too bad--I was looking forward to seeing where they would go next in the
Returns universe. However,
SR still stands as a beautiful ending for the Donner movies--a project I would never have even dreamed someone would make so many years later.
The wording of the announcement was a little vague--it's still possible that Singer and Routh will 'reintroduce' Superman--but I suspect a full 'reboot' is what will happen. The only thing that really concerns me is the idea of taking 'darkness' as far as they can for characters other than Batman.
