I think there is some truth to this, like when Rose and Finn give each other “that look”, once during Maz’s hologram and later with BB-8 in the AT-ST, it sorta makes it feel meta. Like, I don’t think those moments would be as weird without those shots (at least with BB-8, it sorta makes sense with Maz, although Finn just making a grossed out face might’ve been funnier!).

I DO think the topic on humor is relevant, since it might reflect his approach to humor in his own trilogy. Who knows?
