Ever read a book or watch a movie and an explanation is given for something that makes absolutely no sense? That is to say, the explanation is simply flat out weak or stupid. In fact, if the explanation had not been given, the issue that it was trying to explain away in the first place wouldn’t even be an issue. You’d glide right past it, happily immersed in the world of the story. Then this happens, and you start to think, and the holes open up.
Sometimes things are better left alone and the world created in the hearts and minds of creator and viewer alike simply allowed to be.
