Any origin sequence should be done ala The Incredible Hulk(Ed Norton) or something like the montage scene of time passing in The Watchmen.
No one needs a 30-40 min origin scene of Krypton exploding, growing up in Smallville then off to Metropolis.
I'm sure come the second Spidey reboot or next Batman reboot we'll all be saying the same thing about their origin sequences. Those are the next two most widely known and are really getting the screen time the past 20yrs. They have really grown past just the animated route of popularity.
