The Film is quite violent for PG13
Lots of violent and bloody human deaths
A couple get massacred by a A-Blaster in a shower (A lot of blood is splattered, the massacre though is implied, just lots and lots of blood is seen). Including that you see them get thrashed around a lil' bit.
A man throws a machete at one of the A-Blasters and lots of orange blood is splat everywhere, the same man gets picked up and left on a bridge with lots of blood drizzling on him, then later killed. Then the same creature gets shot and killed with lots of blood in result.
An A-Blaster gets shot in the car and lots of blood fills up the car.
Lots of more A-Blasters get brutally turned up into mush by machine guns, rockets and knives.
Same as Graboids and their tongues, they get brutally gored up also.
The Graboid at the ending scene gets struck by lightning and blows up covering everybody in disgusting orange slime.
A man gets dragged out of a helicopter by Graboid tongues and by being killed by them, the blood splatters and paints the whole helicopter red with blood and the pilot.
The pilot gets eaten whole by a Graboid and escapes it successfully by ripping up its belly up with a shotgun.
A man pops out of nowhere from under the ground screaming for help get mauled from a Gabroid as still being in the mauling process, blood and guts fly out from under the ground.
A Graboid gets blown up by a exploding truck.
An A-Blaster is killed by an Bow n' Arrow.
One implied death.
A man gets swallowed whole by a Graboid and doesn't come back out, the man before bing swallowed is crippled up and covered in blood.
