I am a great fan of Charles Dickens' "A Christmas Carol". There is something very special about the novella which is quite hard to quantify. It is a very unique book despite its central theme of redemption being universal. The text has for want of another phrase, a "power" to it. It is profoundly moving, insightful and true. Perhaps the key this story’s appeal lies with the central character, Ebenezer Scrooge. Not because Scrooge is a monster (which are so often fascinating) but because he's a man broken by circumstance. I think readers throughout the years have related to this and considered "There, but for the grace of God, go I".  Cinema has found a rich vein of gold running through this tale, which is why it’s been revisited so often and interpreted so many ways.
