"isn't so bad.."
NightmareMoon is forgotten as villain. and everybody seems to dislike Celestia for banishing her to the moon, and saving their little ponies and Luna(even though she has to wait a thousand years) from eternal night and darkness. So, why don't they just join together and watch all their little ponies starve and freeze to death shall we? Celestia doesn't mind eternal night, as long as it makes her 'sister' happy, and Luna? she's with them as well, but inside Nightmare Moon, all alone.. in the dark, nothing can save her from the dark..
Maybe there will be less hatred for Celestia if she didn't banish NMM, and Luna's probably dead inside Nightmare Moon.
