Comedy is all about confidence. Own your joke, deliver your joke, and move on asap. The problem with “They fly now” is that the joke is done the second Threepio delivers the line. There should be a cut back to the action at that point because your’e not topping that.
General Hugs is perfectly fine, it just goes on too long, too. Star Wars comedy is often very irreverent and of its time (the fact Han is calling Leia sister in Star Wars is some very of-the-moment '70s stuff too. I don’t know that I’d call it “SNL Cringe” but I think you probably could if it was 1979) but what keeps it fresh is that confidence and that timing.
Clips don’t really build hype, and none of the ST clips have either. Clips in general are just like, tiny tastes for talk show blah-blah. I get why we all hyper-analyze them, because we’re obsessives, LOL. But they’re not going to deliver a solid, intriguing scene for free for the late-night circuit. They’re saving those moments for when we buy tickets. This is more like the best of the mediocre-est. That’s what goes out on the press tour.
