Spiderhole – review

In this low-budget British thriller four London students break into a deserted house one night, intending to occupy it as squatters. Unfortunately for them a malevolent force or malefactor locks them in, first terrorising them and then worse. It's a claustrophobic piece in the fashionable sadistic mode of Hostel and Saw – and indeed a saw of the manual rather than chain variety is turned to graphic use, and not for firewood. Murky, morbid and unconvincing.
