The issue you have is DC has been trying to make their universe work together, but until MOS haven't had anything to use as a starting point. Nolan just wanted his trilogy, Green Lantern was a hopeful, but flopped, and they couldn't get anything going. So, they have to reboot. The issue is the reboots come so close to recent films of characters like Batman or possibly Green Lantern that audiences who don't follow comics or just want to see a good movie can easily be confused if they had seen prior version. And it can be irritating to some having to have it explained that those characters didn't exist in this version and are different people.
