Darth Vader scene 1 was dumb and the dialog was very out of place for him. Also, isn't he supposed to have a chain for a cape? Something about the costume was off, but I guess that could be excused by assuming he has changed his outfit over the years.
Darth Vader scene 2 at the very end was great though.
A few too many characters. Seemed like at one point, some of the extra characters got off the spaceship to walk around just to run right back to it and leave, a bit of annoying filler IMO. I did like the droid, and the murderous rebels were a nice thing to see rather than it being a happy Disney story where everyone is clearly good or evil.
Main character seemed way too cocky and spoiled. What did she have going for her other than being the daughter of someone important? I feel like living as a rebel from such a young age would leave her a bit more humbled.
Long range comms: is this a new thing? I don't remember such things from the other movies, and seems like it could change the way the universe works. I'm talking about when the rebel captain guy talked to the main rebel base from his ship when they were light-years away.
Overall rating: better than any of episode 1-3. Worse than return of the Jedi & ep 7, but not a movie I regret watching by any means.
