Time Out says
Capitalizing on the once-in-a-millennium date, this weak attempt at numerological spookiness follows a novelist (Gibbs) traveling 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-porn 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 ten, this film manages to turn it up to you-know-what.
