OK, we saw it this afternoon.
MINOR SPOILER ALERT FOLLOWS:
In keeping with fine Disney tradition, I note the mother didn't make 5 minutes past the opening credits.
MINOR SPOILER ALERT ENDS
Anyway, I thought it started kind of slow. It wasn't until about halfway through the movie that it really started getting compelling. The raid at the end was exciting and had the best spaceship battles Star Wars has yet seen. The acting was decent, but it took a while for the characters to really come into their own. The tie in to A New Hope was fantastic and really well done. The CGI characters (one 'cuz he's dead and the other 'cuz she SURE doesn't look like that anymore) look decent- not *quite* natural, but at least climbing out of the uncanny valley on the happy end.
All in all, well done. I would place it more or less alongside The Force Awakens, below ESB and ANH, but above ROTJ and the prequels.*
*My Star Wars film ranking:
ESB
ANH
R1
TFA
ROTJ
ROTS
AOTC
Literally anything else in all creation with the exception of the Holiday Special.
