So I saw the movie yesterday and fucking loved it. Vader's scenes were amazing.
The beginning seemed a little rushed and all over the place since it was jumping around from so many different places in a short amount of time, but I won't fault the movie for that considering that they only have a limited time to introduce not only the main plot but also all 6 of the main characters in the running time of the film, and once everything is introduced that's where the movie really becomes great. Not saying the beginning was bad, just a bit rushed imo but still good.
I also really liked all of the main characters, it was sad that none of them survived, but at least they were victorious in their mission.
Krennic was a great villain too.
I'd give it a 9/10, I loved it.
