For what it is worth, I am not in favor of this change. I like the Lando introduction and his exchange about sending Leia his love. Sure it is overly nostalgic and perhaps interrupts the pacing a tad, but without this scene then Lando is definitely nothing more than a glorified cameo in my opinion.
It was the “send Leia my love” line that really annoyed me. They never followed it up. We never saw them together, yes Carrie died before filming but they had plenty of option to give us a heartfelt farewell with Lando by her deathbed. That would have been beautiful imo but now it feels a bit hollow.
I understand it ringing a little hollow on the backend of the film as Leia and Lando never get a moment together. However, that is indicative of this entire sequel trilogy; missed opportunities for OT characters to have meaningful interactions with each other. Even though in this case, with Carrie Fisher’s passing this would have been hard to pull off. I enjoyed the line as it was a nice tip of the hat to TESB and how smooth Lando was trying to be when they initially met and how antagonistic their relationship played out throughout that film till the end. This line to me shows that despite starting out as not trusting Lando and even thinking he was in it entirely for himself, they formed a lasting friendship and he became one of her most trusted friends (and vice versa). We missed so much between the OT and ST, lines like this help me film in the gaps between trilogies.
