They fit together perfectly for me. There’s lots of things in Star Wars that require greater suspension of disbelief. Ships fly in space as they would in an atmosphere complete with sounds and fiery explosions and they all have gravity. But we have no problem dismissing these things because it’s a fantasy movie. But I digress. Sorry, I just don’t see anything wrong with the way Rogue One fits with the original Star Wars. No apologetics required. Is it a perfect movie? Of course not. I have no problem recognizing and overlooking the flaws in all Star Wars movies. I just don’t see this one.
