Game of Thrones gives us a vast world full of multiple storylines, scores of characters, and different locations.“Book of the Stranger” gives us a new sampling of that world, as we get every week for ten weeks a year. Some of the samples offered are delicious treats we can’t get enough of, while others we consider with mild indifference—and then there are those that make us feel a little sick. At the next serving, we might get excited about something fantastic we experienced before, but when it’s plated up for us again they’ve changed the recipe, often with mixed results. In “Book of the Stranger” we’re reminded that although something on Game of Thrones may not have agreed with us in the past, the next time it’s served to us we might find it delectable.
