Alden Ehrenreich is not turning me off as young Solo yet. He's definitely cocky.
(Grumble: I do hope they remix the vocals in the cockpit, they sound tinny IMO.)
I'm digging the idea that Woody is going to be the model for the scoundrel that Han eventually becomes (looks like, at least). Glover is so good as young Lando -- that megawatt smile, the bunny ears he does with his droid co-pilot, all good stuff.
The lead baddie looks cool: a wild feral space samurai? Some sneak peaks made some minor connection to Mandalorian armor -- Boba Fett in an earlier guise?
Emilia Clarke's character looks intriguing -- Han certainly has a "type".
