a while back ago, there was a book released, an unofficial look-back at the history of the past superman scripts... McG as director and Abrams as writer, the first script was leaked online. the script had Krypton not exploding, Superman being sent to earth to fulfill a "prophecy",Jor-El and Ty-Zor both fighting a civil war, Luthor not only being a secret CIA Agent but also a Kryptonian spy, the suit-in-a-can concept, and a gay jimmy Olsen... these highlights all were leaked to the public, and the public hated the script. Abrams did change some things around in the second and third script, but unfortunately the damage was done PR wise, plus MCG didnt want to fly... hence, they changed directors (Bryan Singer), and changed to different writers...
there were a lot of things that went into that failed movie attempt, and a lot of those ideas are being implemented into this movie... i for one whole-heartedly disagree with it. there were major problems with that script, and the reason that movie was never made, and the main reason all those other scripts NEVER made it into completion was because it alienated the audience, and only focused on the alien part of Superman, and ignored Superman's humanity. Jon Peters, in the LUITS documentary even admits to this, and admits that he did not succeed in making a movie in the 90's because it was becoming Star Wars, and not Superman. I'm really hoping they're not simply copying previous script ideas to opt out of doing something truly original, because I'm starting to see a lot of similarities in MOS and the past movie attempts
