Like here, with the refrains about how the satire is so subtle and amazing that people don't even know it's satire. I think that's when things go off the rails.
But who is it invisible to? I don't expect those who watched it when they were children to have picked up on these things. And maybe those who were picking their toenails instead of looking at the screen may have missed it. But the satire is not subtle. There are key tells all throughout the movie. MKS has pointed some of them out. Some are thornier to unpack, but some of them have giant lights blinking around them spelling out SATIRE.
As is always the case with satire, a good segment of the population ends up missing the point. A lot of people seem not to like this sentiment, but the fact is a very good chunk of those who consume art are dreadful at reading it. And being that satire is designed to wear some amount of camoflauge, it is consistently one of the most misread and ultimately misunderstood.
The difference between something like Starship Troopers though, is that it actively encourages those who are just accepting the surface message of the movie to hoot and holler out their ignorance, making them all the more obvious to identify. So I suppose it is understandable why so many who respond this way to the movie might be resistant to not seeing it for what it is after the fact. People don't like being tricked. People don't like being made a fool (I imagine especially so when they are made to realize who they were rooting for were essentially the surrogate Nazi's in a film)
Is it maybe bad form for those who do pick up on the satire of this film to laugh at those who don't? Maybe. It's certainly a very cynical ploy of the movie. But I also understand the deep frustration of those who picked up on the films obvious clues, and enjoyed the movie (which, as I said, I was fairly medium on) having to engage in a conversation with someone who keeps citing it as nothing but a big dumb action film. Maybe they liked it because it was big and dumb, maybe they hated it because it was big and dumb, but this is what ultimately is going to get fans of the film to double down on citing its 'brilliance'. Because I imagine that's what some people feel like when they are in the middle of an argument with a bag of potatoes.
There is also the fact that, considering what the result of people blindly accepting whatever it is they watch as long as if it feeds them enough endorphins and gives them enough catch phrases, is literally fascism. Or all other sorts of politcal horseshit. A movie like ST is exposing the weakness in the populace that gets exploited by those in power, making it very visible, and this can cause an even extra level of distrust and frustration with those who simply don't 'see it'. And just as we've seen in recent times politically, the fissure that develops between those who smell the stink of the ruse, and those who eagerly jump upon it, ends up forcing both sides to double down into complete and total ****ing stupidity. So, even though I'm sure this was not planned by Verhoeven, even the audience reaction is a microcosm of the town hall, where everyone just screams at eachother and think they are right. A claim that maybe nobody is really even entitled to anymore.
Basically, as I said, I think it is effective satire. I would never go so far to call it brilliant. So I'm an agnostic on that front. But I also just don't know how effective an argument it is to focus so much attention on the worst takes of the worst viewers in order to discount the claim. I'm sure MKS could continue to add to his argument in defence of the genius of Starship Troopers. And even though it might not compel me towards that conclusion, or you, or Yarn, and certainly not those who won't acknowledge the satire in the first place, I think there is a good case for why he thinks its brilliant. And it wouldn't just be because he is patting himself on the back for seeing the movie for what it obviously is, or that he doesn't understand how satire properly functions.
