Lando was just a cool guy who ran a city and sold out our friends.
Yeah, and that’s a pretty damn important part of the plot!
I know, the point I am trying to make is that he has the exact plot enabling role as Rose (see Dom’s posts). Ok not exact, as Rose probably has even more plot enablement.
So considering that a tie between Rose and Lando, I will use my personal preference to pick Rose as more interesting. Less cool probably though, I am sure most of us thought Lando was a pretty hep cat. (Am I saying that right?)
