It seems to me there was quite a bit of name dropping in there. I can recall hearing Bossk and Aura Sing mentioned. I'm probably just blanking on a bunch of other names I probably should know.
The funny thing is they name dropped a few bounty hunters but only referred to Jabba as a new high time gangster on Tatooine. Only reason I could see was they wanted to keep the timeline murky.
@FTJ: Play SWTOR if you want to see a bit more of how Corellia can be. Not quite movie realist CGI, but you get the same feel it gave in the movie.
Saw it opening night. I enjoyed it. Donald Glover was brilliant as Lando. The acting all around was good. Felt like Ron Howard made a mark when they upgraded into him as the director. The whole Kessel run seems a bit too fast paced. Emilia Clarke's Kira character path was the only real shocker to me, but I saw seeds of her actions at the end throughout the movie. She has serious training in Teras Kasi, wonder if she might be FS......
The Maul thing was the only thing I honestly hated, but this is the new Disney canon, they can retcon whatever they please (unless the movie's timeline is before Rebels, where they did kill the bastard off finally we thought)
