The nifty part is how the Russo bros are not only fans of Honest Trailers, but specifically made sure the movie wouldn't have any plot holes for Screen Junkies (who run the channel) to make fun of. Now, HT found a couple anyway, because that's what they do. But mostly, because of the Russo's diligence and paying attention to their own goddamn script, the parody actually praises the film.
For comparison, Age of Ultron didn't come off nearly so well, though the Screen Junkies were admittedly sympathetic with all the different threads Joss Whedon had been forced to pull on when he made it.
The thing is, though, why don't more producers and directors (and studios, for that matter, since they all ostensibly work together) do this? Making sure your film doesn't have enough plot holes to give a parody channel much to work with seems like a no-brainer. Hell, I try like hell to avoid plot holes whenever I write anything, and I'd love to be famous enough for my work to be parodied to thousands of viewers.
Well, okay, maybe not. But the point is that one of the big things I worry about with my own plots is what I call 'internal logic', which is just making sure that all the elements in the story make sense. I know that some films have that harder than others, especially when, say, setting up three different future plots at the same time the way AoU had to (Captain America: Civil War, Thor: Ragnarok and Avengers: Infinity War, though I still could've done with less Hulk fighting Iron Man and more justification for his out of the blue relationship with Black Widow).
But that's Age of Ultron. I don't think, for example, that Green Lantern necessarily had that issue. But it's internal logic was so poor, it ended up with a lot of other issues.
A lot of other issues.
