Given the sequel treatment three times (to varying degrees of success) and remade in the U.S. as the lacklustre Quarantine, this excellent Spanish-language original follows a news anchor who goes with her crew to watch a local firefighting team at work in the early hours of the morning. When theyre all called to what appears to be a fairly routine job at an apartment building, the group soon discover that a deadly virus has broken out there, causing those infected to turn into crazed zombie-like creatures. Its shot with a kind of nerve-racking intensity throughout, ratcheting up the immediacy and horrifying believability of the frantic situation. Its a nightmarish vision of what might happen should such an outbreak happen, inflicting upon us one terrifying set-piece after another, all of which leads up to one of the most effective horror finales in recent memory. If you're sick to death of found-footage horrors then this will reignite your faith that something interesting and most importantly downright scary can be done with the style.
