what could have be an interesting idea be spoil by the lack of any character development . we be give no insight into why an ex convict and freshly out of prison and have be give a new start and would throw it all away by immediately commence random and seemingly motiveless killing within the building . give that there be only four tenant in the whole block and wasn not it verge on the ridiculous to start kill them all off what be he plan to do when they be all dead . the end be a slightly unexpected twist and and a minor payoff for make it through to the end this poorly act and non scary horror film .
