During the party, the camera zooms to a sleeping woman with half breast is sticking out of her blouse.

Severe graphic violent monster action throughout.

Bloody, brutal and graphic.

We see an enormous creature standing in a city street; smaller creatures drop from it, skitter across the ground, jump on people and bite them (we hear the creatures screeching, the people screaming and see the people writhing during the attacks).

While in the safe house, a man's brutally mutilated corpse is seen on a stretcher very briefly.

Four people walk through a very dark subway tunnel, they hear noises and see rats streaming past them, they then see creatures moving along the ceiling toward them, and the creatures drop to the ground and attack them: a young man is knocked to the ground and a young woman beats one creature to death, a young woman is attacked and bitten (this creature is also beaten to death), and the four people run away, crush another creature in a door (blood spurts and covers the camera lens) and hide (each of them has a bloody wound and one young woman has deep, bloody bite marks on her back).

A small creature drops from a ceiling toward four people, a young man beats it with a fire axe and we see the creature writhing and hear it screaming (goo or blood splatters on the wall behind it).

The characters are taken into a hideaway, where several people have bloody wounds being treated. A man's brutally maimed corpse is show being wheeled on a stretcher briefly onscreen.

People crowd onto a bridge and try to move across it, one of the vertical supports is pushed down (we see a young man crushed and taken down by it), the bridge begins to collapse, people run frantically back, and many fall as the bridge falls into the water below.

A character's girlfriend is found with a metal rod protruding out of her chest (blood is seen on her shirt), before the characters yank the rod out of her, with blood and pus spurting out.

From an aerial view we see many bombs being dropped on an enormous creature, the creature is struck, it leaps into the air, grabs onto a helicopter and forces it to crash (we see the scenery spinning and then the rubble afterward) and there are survivors but one is badly injured (we see blood on his head and leg).

Intense circumstances yield many exclamatory profanities, such as "g-d-n," more than 30 uses of "my god," 20-plus uses of "shit" and a half-dozen misuses of Jesus' name. A few milder swear words pop up, too, and Jason calls Rob a "douche bag."

Many people are shown drinking alcohol (beer, wine and liquor) in an extended party sequence in the beginning of the film

The found footage style of the film could make some viewers nauseous. When the film was first released, people were leaving the theaters because the camera motion made them queasy.

The scene in which the three main characters try to cross from one building to the other is intense.

The movie itself is hauntingly realistic, as it depicts the panic and terror of people amidst a crisis. Some scenes are very reminiscent of the 9/11 attacks as well. This is one of the most realistic, and terrifying monster movies ever made.

The iconic scene where the Statue of Liberty's severed head flies into the middle of the street is very sudden and intense.

The film as a whole has a very dark and depressing tone.

After the first 20 minutes, it stays intense and frightening throughout.

Small creatures drop from the monster that attack and bite people. The bites cause harmful effects to humans. Their appearance and movement may be extremely unsettling to some viewers.

The whole movie is photographed on a home movie camera. The camera is very shaky (especially at action scenes). That may cause motion sickness.

The overwhelming sense of fear and dread felt throughout the movie could possibly even classify this as a horror film.

The initial monster attack comes out of nowhere and completely without warning. It is very shocking.
