Not much has changed at Lucasfilm pre/post Disney, even though it may seem like it.
Most of the people who worked on the ST also worked on the PT. It’s half the reason the ST was made, and probably 100% of the reason Star Wars was sold to Disney, so that they’d still have jobs after Lucas retired.
It’s like…anime. I like anime, but it’s horrendously rife with “serious moment…then you MUST break the tension with sight gag/dialogue.” I’m betting Rian must be a hardcore anime fan.
I found the humor in TLJ more akin to the one present in some Marvel movies. The MCU entries are full of bathos and comic moments that break the mood of serious or dramatic scenes (Thor Ragnarok comes to mind).
TLJ, Marvel, and anime all have bathos, but they all use it in different ways, and in different amounts.
