Appear in: Starship Troopers (1997)
Scariest moment: An endless army of pissed-off alien insects charges toward the steadily firing soldiers' bunker.
Weakness: Unsubtly veiled propaganda.

For a movie that, on the surface, seems like one you'd watch on the SyFy network, Paul Verhoeven's Starship Troopers is terrifically clever. It's pure modern-day propaganda, a military recruitment video masked as a special effects science fiction extravaganza with endless swarms of large insect enemies dubbed "the Bugs." Attacking the futuristic human soldiers with overpowering vigor, Verhoeven's creepy-crawlies never kill someone without leaving a gooey, blood-red pool of guts and limbs behind.
