As both a story creator and a story consumer, I love bookends and circular themes; that is to say, I love it when a story is set up so that the ending is a parallel to the beginning. This is due to two parts:
1) history is constantly repeating; people live, love, fight, and die. A bookend story helps to reinforce this idea.
2) while history is constantly repeating, people can learn from previous mistakes. A good bookend story takes that idea and makes the ending smarter, better than the beginning was.
Take GoT for example, and more specifically: Jon/Sansa
