i hate this movie . it be a blatant attempt to rip off die hard and and fail miserably . some guy be in a building kill everyone . we do not know anything about him and we do not know his motivation and he just apparently want to kill people . so we have a woman trap in a building with a killer and monkey . and all this have to fill a couple of hour . the plot have serious credibility problem and and the end be stupid and pointless . avoid this movie unless you have see all the other movie about people trap in a building . even anna nicole smith skyscraper be well .
