"Disaster Movie" is a spoof movie by Aaron Seltzer and Jason Friedberg.
Coming from an era, in which there was a huge amount of parodies, all of which were critically panned, "Disaster Movie" is nowhere anything special or original. Still, some of the spoof movies were simply underwhelming, while many others were only stupid and unfunny. "Disaster Movie" is the second one. While Seltzer's and Friedberg's earlier movies, like "Epic Movie" or "Date Movie" still had some good jokes, "Disaster Movie" is rather a marathon of how many films, series, celebrities and pop culture events to refer to in 70 minutes of running time (excluding the much too long ending credits). There are not even attempts to add jokes to the many references, they simply throw together characters from other movies, peppered with some politically incorrect jokes, and even those are not any intelligent or satirical. The movie's quality is rather bad, having obviously fake special effects, a man in a fursuit starring as Kung Fu Panda and unrealistic dolls as the chipmunks. The movie's structure is terrible, without having a real plot or anything to hold on to. It's just a parade of three "original" characters, a bad Juno parody and a drug-addicted version of a Disney princess running through a town, meeting several characters from other films and series. The few funny scenes, including an actually hilarious parody of the "Head On"-commercial, can't make up the many mistakes the movie did.
Even for fans of Seltzer and Friedberg, it is annoying it is annoying to watch. In each of their other movies, there are at least some positive aspects, enough for saying that they are simply "not good, but not the worst", but "Disaster Movie" really is way ahead of this all. It is a quite unfunny with annoying protagonists and way too many parodies to create a real plot.
The movie has a lot of sexual and violent humour, though.
Several references to sex that do not go beyond what is suitable for teens.
Nothing is seen. Nudity is seen, but only from behind or pixelated. One of the protagonists is a prostitute. References to beastiality (the animals are anthropomorphic).
There is pretty much violence, but it is for comic reasons:
Several characters are shot by accident. One character is shot in the head in slow motion (no blood, but the wound is explicitly shown). Another character is shot in the head (we briefly see the wound).
Several scenes of disasters. Explosions, meteors fall down, usually bloodless. At least two characters are crushed by meteor (no blood).
Several limbs (obviously fake) fall down on the street.
A girl eats a bottle and she heavily bleeds from the mouth.
The same girl has her feet cut up from the glass shoes she wears.
Several characters get attacked by the Chipmunks - one has her back torn open (we briefly see the non-graphic bones).
A characted is repeatedly shot with a gun and the girl who shot him is very satisfied - kind of glorifying violence, but so over-the-top that it is clear that it is meant ironically.
A transgender and a pregnant girl fight brutally.
A man has an axe hit in the back.
A girl is whipped accidentally (a scratch is seen on her face)
Several scenes of bloodless violence.
The language is not that bad in the PG-13 version.
In the Unrated version a song is sung in which the characters sing about having sex with each other and use the f-word a lot. In the PG-13 version the f-word is replaced by "dating".
A girl makes several strong references to drugs that can seem glorifying, but are just satirical.
As teens can make a difference between a comedy and a serious movie, it is okay for viewers 13 and up.
