Apollo 18 is a sci-fi horror movie shot in the style of "home movie/documentary", sometimes referred to as a "mockumentary".  Apollo 18 deals with a fictional moon misson after the last one (Apollo 17) that ends in diaster.  Being filmed as if it was actually filmed in the 1970's, Apollo 18's film quality seems low.  Like the actual Apollo missions, there are only three astronauts in this movie so they are in the majority of the scenes (with cut scenes showing family, some early scenes showing other NASA personnel and military men). 

The premise is that while NASA officially canceled the Apollo program after Apollo 17, the military wanted another mission to the moon so they get NASA to send Apollo 18 as a top secret mission (with the astronauts' families not even realizing where they are going).  True to form, like real moon missions, two go to the moon and the third stays in the rocket capsule.  When they get to the moon, they quickly realize that the Soviet Union has been there but something has gone wrong with the Russian's mission and strange things begin to happen to them.

Unlike other "mockumentaries", like "The Blair Witch Project", the characters in this movie actually knew they were making a movie.  This does mean, as mentioned, that some of the camera work is shaking (thogh not nearly as bad as Blair Witch or Cloverfield), grainy at times and may even has distruptions.  This also means that clarity is an issue so when something happens, there is a chance you might miss it or wonder what it is.  That works though, as the filmmaker is trying to convey a sense of danger, of being along, and not know what is going on. 

Being a "mockumentary" style movie, the filmmaker also hired relatively unknown actors (as famous actors playing the roles would take away from the feeling this actually happened - most have done theater or TV series prior to this movie).  This also means that the acting quality isn't on par with some other movies but it's not bad either.  They aren't just random off-the street people they found, they are seasoned actors.   The film stars Warren Christie (October Road, Happy Town) as Capt. Ben Anderson, Llyod Own as Commander Nate Walker and Ryan Robbins (Stargate Atlantis, Battlestar Galactica) as Lt. Col. John Grey. 
The horror aspect of the movie comes from two places.  The first is the sense of the unknown and the second is the sense of isolation.  They are two people on the moon and no one is around to help them if they get into trouble (they do!).  While not a constant edge of your seat horror movie (there are some slow parts in it) there are a few parts that make you jump and wonder what just happened.

Overall, Apollo 18 is a decent horror flick.  I think they could have done a bit more with it but for the director, Gonzalo Lopez-Galleo, this is his first major motion picture and he did well with it.
