This is what you call milking every last drop from a hit series:  HBO has announced that a 2 hour “Game of Thrones” documentary will air a week after the season ends.   “The Game of Thrones: The Last Watch” will air on May 26 to give you one final look behind the scenes of the popular series.   The documentary is said to be more of a feature film than your typical look at a show behind-the-scenes.   Are you ready for the final season?   Did you go back and watch any previous seasons so you are familiar with the many, many story lines?   -Mitch-
