A very late first watching yesterday night with the wife.
I loved it!
The Rebels and other cameos in particular, K2SO, the U-Wing gunner, the first appearance of the AT-ATs, the AT-ST (one of my favourites), the transport and the Hammerhead Corvette - hope they make these for X-Wing.
I missed seeing Chopper and the Ghost, so I'll have to see it again of course.
It was darker than I expected - I always felt it had a Seven Samurai feel (no prizes for guessing why!) to it and expected many of the characters to die, but not all of Rogue 1.
The greater callousness of the rebels and the disagreement on Yavin eliminated what I felt was a slight degree of blandness to the rebels' character in previous films. And one scene I found particularly dark was K2SO digging into the memory of a twin robot nonchalantly.
The aesthetics - it looked like the 70s tuned up - the hairstyles and moustaches were spot on!
