Is a remake usually better than the original? The Spanish language film [REC] was remade as Quarantine for the U.S. market.
[REC] continues in the recent horror trend of found video footage (started by The Blair Witch Project I think). In this scenario, the story begins innocuously when a soft-news tv reporter follows some firefighters overnight. The reporter, Angela, hopes to get some exciting footage although the firemen tell her most days it is just waiting around. A call does come in though, a report of an elderly woman who locked herself in her apartment, and Angela and her cameraman Pablo excitedly ride along.
When they arrive at the small apartment building, most of the inhabitants are gathered in the foyer with a couple policemen. Things are a bit confusing but they go up to the woman’s apartment, she is a bit incoherent and they approach her carefully, but suddenly she goes berserk and fiercely bites one of the men. As everyone tries to make sense of what has just happened, they discover that the building is in lockdown, with policemen on the outside telling them to stay indoors, that some sort of contagion is loose in the building.
As the film continues, it comes out that a sick dog may have been Patient Zero, spreading a rabies-like virus that is causing the havoc inside the building. Meanwhile, Angela naturally has Pablo continue filming the story, giving on camera commentary when she can. It turns into mayhem and she and Pablo become less of journalists and more of victims like the others, as they accuse each other, hide secrets, and try to get as much info as possible from the people outside. We see, through their camera, as a health technician is sent in to tend to the injured victims, but that he really has something to hide. One by one, they are picked off, and as they get infected, they become killers.
