At last, someone has thought about the fans who grew up with the original films. Rogue One is a prequel to A New Hope that shows us how the rebels captured the Death Star plans and it literally ends just before the classic opening scene.
This really is the Star Wars movie you're looking for.
It also introduces a few shades of grey to the saga, as the rebels are no longer the righteous freedom fighters we saw in the originals. Overall, it's a grown-up film for grown-up fans but no one's ever too old to be excited by X-Wings and Tie Fighters.
