In the Early days of Xbox 360, Microsoft added a Netflix feature that allowed you to add people to your party, and you could all view a movie, or episode of a show together. Your Avatars would sit in a "Movie Theater", and watch it together. Many people would love to have this feature back, including myself. With a rework, and streamline of the feature, I do think it would be quite popular, with big shows hitting the Spotlight, having a party to watch it with would be an awesome way to bring together your Irl friends, and online friends.
