2 / 5 stars
(Cert 18)

Where next for a pair of young directors fresh from shooting the Spanish version of Pop Idol? For Jaume Balagueró and Paco Plaza, the answer is simple: make a reality-TV zombie movie in which everyday folk preen gamely for the camera before being munched to death by the monsters in their stairwell.

Manuela Velasco stars as the blood-spattered presenter, desperately trying to maintain a professional air in the face of mounting carnage, like Konnie Huq at the Olympic torch relay. But midway through, the plot blows a gasket and the camerawork turns altogether crazed, joggling us about in the semi-darkness while the soundtrack rings to distorted screams. Expect pitch and yaw and lots of gore.
