Anyways finally saw it today. It was good but I still liked The Force Awakens better. Just a matter of setup really, TFA gives me characters to care for and a continuing storyline, while Rogue One is more a one & done movie.
As far as the overall Star Wars story is concerned, I really like how they patched up one of the bigger plot holes in the originals, thought that was rather touching.
Speaking of plot holes though, did I see that wrong or was the Death Star simply stationed and with the construction being finished above the Jedi temple planet? Consider that Cassian's ship was able to simply approach and land on a planet that was an active rebel war zone, having the Death Star hanging out in orbit doesn't seem like a very good way to keep it a secret guys.
