There's something refreshing about a Star Wars movie that's set in a familiar universe but which doesn't involve any familiar characters of plot-points. Such is the case with Rogue One: A Star Wars Story, which is slated for a December 16 release and which received a longer and more intriguing trailer above.
Aside from a split-second of shot of Darth Vader, most if not all of the characters in this peripheral story are new or have just been alluded to in past films. Rogue One also takes place between Episode III and Episode IV, so it shares the 70's set design and aesthetic of the original Star Wars: A New Hope. Personally, I wasn't too excited about this movie, but the second trailer has me intrigued and I think this movie will surprise a lot of old and new Star Wars fans.
