Its partially the fans fault. I ( and i'm sure others here) can remember back when burton was onboard, then ratner, then etc etc. The fans hated those ideas and wanted someone to continue on with Donner's version of Superman.
That led to W.B. hiring Singer. He had the right idea, but it was executed poorly.
IMO he underestimated what the public wanted, and that was a Villain that could stand toe to toe with the man of steel.
If we get another, I have no doubt we'll get just that, which is a supervillain(s) and loads of action. I just hope they dont go from one extreme (too much drama, too dark) to the next( too campy, cartoony)
