Sexy, Sex and Nude Scenes
A photo is shown of a man having anal sex with an alien. This was a prank, and is shown for 2 seconds, as well it lacking in explicitness.
Violent and Bloody Scenes
Most of the violence in this movie is EXTREMELY over the top and cheesy, due to excessive alien gore.
The crustacean-like aliens bleed red crimson blood just like humans do.
The aliens possess weapons capable of blowing people up; the weapons are used several times in the film. The aftermath of these deaths are bloody, but they are comically over the top.
We see an alien rip off a man's arm from a distance with lots of spurting blood. We see a close up of the severed arm with bloody tissue hanging from the stump being placed in a garbage bag.
Two small alien creatures fight. One drives it's spike tipped tail into the other with spurting blood.
A cluster of alien eggs is burned with a flamethrower. We hear the unborn babies shrieking as their eggs pop.
An alien attacks two men by hitting them with the butt of a rifle and flinging them through the air. One man receives a broken arm from the attack.
An alien is shot in the back with a rifle. He is then shot in the head at point blank range splattering blood on the camera and on the ground. A pool of blood forms around his twitching body.
A man's arm violently mutates with lots of secreted blood.
Scary and Disturbing Scenes
Several scenes where helpless and defenseless aliens are killed.
A man's transformation into an alien may be highly disturbing to most people.
Various things happen to Wikus implying his transformation. It is somewhat disturbing.
Wikus is presumed dead, but eventually implied to be okay. The film's ending shows what is apt to be Wikus, fully transformed into a prawn.
The prawns alone are frightening, especially to young children.
14+ if they can handle the swearing, that's the worst part of the movie.
Saying this movie is good would be an understatement. The movie has it all, a very intriguing deep plot, good acting and great action. If I was to find a flaw in this movie, it would be the shaky cam technique employed at the beginning part of the movie and also at the very end. The shaky parts are supposedly documentary clips telling the story of Wikus, the protagonist. But rather than add to the feel of it, the shakiness is just nauseating. They just over did it. But after a while into the movie, they got out of the documentary mode and things couldn't be any better. And the special effects in his movie will have you believing that these aliens are real.
It's better that you go into this movie not knowing the deeper plot as a big part of the movie's entertainment value for me is the parts when things look hopeless and you really feel the despair and hopelessness of the characters. The only thing you need to know going in is that there are aliens stranded on earth and they are put in slums.
This is one of those movies that teases you that it's nearing its end, but inside, you go "No, I want more. It can't end like this", and the movie hears you and gives you more. And it's primed for a great sequel. The potential that this franchise has is just enormous. The way they can expand the story is just limitless and all of them can add to it's lore. This is a classic franchise in the making.
