What makes Earth Prime so important?
How does destroying Earth Prime destroy all of reality? I know that all the heroes conveniently reside on earth, but that shouldn't mean that Earth is like the center of reality or whatever.
There are other planets in the DC universe that are as important or more important than Earth. What about Krypton? Krypton has existed at least 1000 years before Earth has? Surely there are Kryptons that haven't been destroyed?
What about the World Headquarters of the Green Lanterns, Oa? Shouldn't the Prime World of that be important?
If anything, destroying Earth Prime means that the other Earths would get destroyed too, but not all of reality.
In the end, it's an interesting concept, and the movie was enjoyable, but it's been bugging me recently.
Time spent dreaming is time wasted.
