Like just about everyone else, I watch Game of Thrones, and both can't wait for and dread the finale on Sunday. George R.R. Martin created a rich world with characters that are fierce and fascinating and complicated. Although it's set in a fantasy world, the show has examined a number of interesting themes around very real-world issues, particularly on power and leadership. Really, Game of Thrones is an extreme competition between family businesses. Taken in the context of business, the residents of Westeros and Essos have a lot of powerful advice.
