Don't bother, he's forgotten to attach a huge IMO behind all of his comments.
-a prequel origin, with Routh, that would re-conceptualize everything in SR could work very well. A prequel Origin would severe the ties with the Donner franchise instantly. Moreover, with the ability to rewrite every SR character's history, through the prequel, there are many interesting possibilities that could be changed. 1) I'd love for a prequel to redefine Jason as a Superclone that Lex implanted in Lois through a mad scientific rape, 2)if Superman does not know his true origin (other than a spaceship) in the prequel, his motivation to leave and find krypton would make a lot of sense, given some creative writing, 3) Lex could easily be dealt with. Perhaps Lex was the evil businessman we all know and love, but that before SR Superman's interference with his plots may have driven him a little MAD.
This works better than a straight reboot(the concept, not my examples), because although SR didn't work out as well as it should have, it would be a waste of money just to throw it in the trash and forget that it never happened. A HUGE WASTE OF MONEY.
Basically what I'm saying, is a good writer could take SR (a substandard movie) and frame it between a prequel origin which would severe the vague history BS, and a post SR sequel. Between the two frames, the outlook on SR could be vastly improved. It just takes someone intelligent to sit down, and write a pre SR origin, so that the Donner franchise no longer exists in the SR continuity (replaced by the prequel origin)
lastly, we shouldn't be afraid of prequels, just because some dumbass decide to prequelize his brilliant story, and ruin it in the process. This is not Star Wars, and it doesn't have to be. The prequel can work. It just has to be made by someone who cares about the story, rather than selling action figures and lego to 4 year olds.
