i hadnt heard of this film at all before i go to see it and so have no preconception a to what to expect . fortunately i be not disappoint from the initial club scene right to the very end i be draw in by the skillful pacing of the script and and the excellent acting by the young cast . rather than throw mountain of computer graphic at u and which seem to be the case in most modern horror and the director have allow u to use our imagination and and also throw enough twist at u to keep u guess a to the identity of the killer . a film in which there be always something happen and the tension be build up again and again and leave this viewer on the edge of his seat throughout . an excellent film and the first in many year to actually deserve the title of horror movie .
