VAGUE SPOILERS BELOW:
Rogue One was great.
Had a little bit of a Transformers: The Movie feel to it in regards to how many main characters may or may not get killed off by the end of it.
Chirrut Îmwe is a fucking badass in it. He’s my new favorite SW universe character.
And, yes, Vader is in it. And, yes, he goes absolutely H.A.M. toward the end of it. And, yes, this alone makes the movie totally worth seeing.
