Scariest moment: In this case, "scariest" is used loosely. A more apt word would be "funniest," or "best scene in which the filmmakers threw their arms in the air and said, 'Fuck it.'" During the climax of 1986's Critters, two of the titular beasties are about to bum-rush a house, but there's a problem. "They have weapons," one says in their indecipherable language, right before a woman blows the other Critter away with a shotgun. The surviving one's response: "Fuck!" Pure genius!
Weakness: Human feet (which can just punt them with ease).
Aren't those little bastards cute? Sure, especially if you used to collect those old Troll dolls and always wished that they'd have sex with Stripe from Gremlins and start biting people. The puny, carnivorous monsters are members of an alien race that's blessed with the ability to roll with motorcycle-like speed and launch the spikes on their backs as pointy missiles. Silly, yes, but also the last kind of animal you'd ever want nipping at your heels to play Fetch.
