These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crosses the Line Twice: The time bomb that announces it's a time bomb and reads off its own countdown is hilarious. Even Rico winces over it, as he's dropping it. It is described as a terror weapon. It isn't intended to kill the enemy, its purpose is to scare the shit out of them.
Jerkass Has a Point / Strawman Has a Point: Even readers who disagree with the book's heavy-handed political statements are likely to find the book thought-provoking based on how, exactly, they disagree.
Aliens is often considered to be the most faithful adaptation of Starship Troopers ever made, due to the various similarities. Now, on the flip side, the Space Marines of Aliens themselves were the inspiration for other Space Marines, such as the ones in the film of Starship Troopers.
Halo owes a lot to ST, especially with the armor and ODST's drop pods. Its spinoff game Halo 3: ODST featuring those shock troopers fighting the Drones.
Starcraft has plenty of references to and points of inspiration from ST as well.
Along the same lines Paul Verhoeven has commented on how based the Propaganda segments were modeled after those played in historical authoritarian regimes during wartime and also how he set up the Bugs to be clearly superior in every way to the humans opposing them. Combining the two together can imply that the Surprisingly Happy Ending portrayed in the final Propaganda cut scene is simply a case of the Government trying to hide the Awful Truth of the probable defeat.
Anvilicious: Paul Verhoeven knows of no other way to present a message.
Though for some people the message is still lost, and the movie appears to be a gung-ho sci-fi romp in which War is Awesome.
"Funny Aneurysm" Moment: In-Universe example in the first movie: the recruitment commercial with the cute, eight year old kid in uniform saying, "I'm doing my part, too!" and everyone laughs. Cut to the last battle in the movie where Johnny and Ace command a squadron of Child Soldiers, not much older than that first kid, and it's not funny anymore...
Misaimed Fandom: Despite the fact that Paul Verhoeven is anti-war and anti-fascism (likely from having bombs dropped by the Allies in his backyard as a child when aiming at fascists), people will accuse him from now until judgment day that the movie glorifies war, fascism, and blind, jingoistic patriotism. To think Paul Verhoeven made the mistake of being too subtle.
"Luckily, the script writers realized what they were working with and wrote some of the cheesiest, most badass dialogue in any movie ever. I don't know how they did it, but every single line in the movie is completely corny but awesome at the same time. This results in the audience getting a good laugh in the fifteen minutes of the movie when people aren't getting their arms ripped off or aliens aren't being exploded into pieces and spewing green fluid all over the place."
Special Effects Failure: The sequels to the original, and "Marauder" to "Hero of The Federation" (though only because "Hero" bought back Tippett Studio for the bugs)... Additionally, since the majority of the bugs were created via CGI, and thus, were never on set for the actors to aim at, the troopers often end up pointing their rifles over the bugs' heads during the battle sequences.
What The Hell, Casting Agency?: Casper Van Dien, Denise Richards, and Neil Patrick Harris playing Argentinean high schoolers... Verhoeven aimed for a Do Not Do This Cool Thing-baiting feel with the casting, going for stupidly beautiful people who would be far more at home in a soap opera — and then not telling them the film was a satire, leaving them to play their roles deadly serious.
