There are million jokes running through my head about 50 Shades and torture at Gitmo. However, I think the popularity of the series is due to the popularity in the U.S. (even if a year or so behind). I remember reading a few years ago that the Harry Potter series was also popular at Gitmo. This is why some countries try to block Western content and culture. Some say rock music and denim jeans did more to topple communism than diplomacy.
