when i buy this some time ago ( have to order from the uk ) and i wasn not sure what to expect . slasher or what . i be pleasantly surprise with the result . it have some genuinely creepy and disturb moment from the start and and the whole time youre keep on your foot a to what the hell be go on . i can not explain it . i be think oh sht . the entire movie . it quiet and it intense and and surprise even the most seasoned horror fan and though i wouldn not categorize this a such . paddy character be both welcome and menace at the same time and a perfect act job and he should have receive some recognition for this . instead american audience know almost nothing of this film . i have become such a fan of paddy considine and will watch whatever he come out with from now on and he simply make brilliant choice a to what to associate himself with . there a lot of passion on his part . that alone make for a worthwhile viewing experience .
