A massive ball of furry creatures from another world eat their way through a small mid-western town followed by intergalactic bounty hunters opposed only by militant townspeople.
The critters eat a cow, some chickens, and a goldfish. The kills happen off screen, except for the goldfish. You only see the remains of the cow shaking as the critters eat, and a person shines a flashlight on the remains. You don’t see any chickens, just a critter in a henhouse and feathers flying. One critter dunks its head into a fish tank and pops out with a goldfish in its mouth, then slurps it like a spaghetti noodle.
If needles trigger you, then the critters having poison body spikes/darts they can shoot at people might have similar trigger effects. But there aren’t any syringes with needles in this movie.
Charlie the town alcoholic talks about hearing messages through his tooth fillings which other people think means he is mentally ill but it turns out his fillings do actually react to alien communications
The word "sh*t" is used multiple times in the move and "f**k" is used once however in the critters language so it isn't heard but rather is shown in subtitles.
There are a lot of flashing lights in the movie. Holograms, police lights, alien gunfire, bright explosion, and the title card are a few examples. There is also a scene in the beginning of the movie that shows the one of the bounty hunters rapidly flipping through images and sped up clips of earth's history.
In a few scenes the camera takes the view of a Critter and shows them stalking characters. In another scene a Critter is seen in the background watching a character that is unaware of their presence.
