What would it take for me to like a Superman movie made by Singer?
A reboot with a short origin story told with drawings by Alex Ross (like the opening for S-M 2).
The world has to be set in the TAS world, maybe not that utopic from the start. Have Zod fight Supes and led to the destruction of most of Metropolis. It's rebuild by Luthor, who will bond with Supes in the end of the first movie and later become President.
From there on introduce more of the Krypton heritage and let Clark even find Kara. She's maybe trapped on Warworld and Supes has to fight Mongul!? Luthor turns on Spues in one of the movies and keeps working against him by hiding behind his status.
Have Clark and Lois start out like on "Lois & Clark", leading into a releationship and finally the marriage. Once that whole love story thing is done there's enough screentime to build up the JLA.
Start it by introducing B-List heroes like Shazam, Aquaman and Green Arrow during the first movies. Flash, GL, Wonder Woman and Batman should finally appear in the last 2 Superman movies, helping him to fight Darkseid an his army and to set up the JLA movie(s).
Luthor will be brought down by Superman and Batman during or before that.
Just a short list of things I expect from a Superman movie in 2006. A Superman movie is pretty much a no-brainer. You have ~80 years of history to draw from. So sad many people still live in the 70s with that boring old movies.
