I like Rogue One but telling the story of how the rebels came into possession of the stolen plans is completely unnecessary, the crawl for Star Wars 77 does it well enough. Also all the characters die, its almost impossible to genuinely care about their fate, its a one and done film. I like the characters but they are surface level archetypes at best.
I wasn’t expecting much and it is Star Warsy enough, probably the closest looking thing to real Star Wars since Empire Strikes back in the design esthetic of a real and gritty used universe. Vader going all prequely at the end kind of ruins the start of the original film though.
