Capitalising on the once-in-a-millennium date, this weak attempt at numerological spookiness follows a novelist (Gibbs) travelling to Spain to see his dying father; he soon connects recent tragedies to the belief that the portals to heaven and hell will open once all those ones show up on the calendar.

A veteran of the Saw franchise, Darren Lynn Bousman trades torture antics for an old-fashioned Euro-horror vibe, complete with old dark houses and creepy maids; he then wastes what little suspense he generates with endless dorm-room philosophical debates about faith versus atheism and religio-conspiracy theories so far-fetched they’d embarrass Dan Brown. If the ineffectiveness knob goes up to 10, this film manages to turn it up to you-know-what.
