I can see why they wanted to keep the franchise close to their vest, or cape, as it where.
The budget was so f'n high. Plus they dumped cash and time into screenplays from Kevin Smith, JJ Abrahms, directors like Tim Burton and McG. I think even Nick Cage had a pay or play contract at one point.
The studio kept it simple with Luthor as the villian. I can see that.
Why reboot now? Keep the dude who played Supes, maybe dump the chick who played Lois. Have Brainiac smash shit up.
-HECK!
