there be a total of one roach that ever show up in this movie . the only scene involve a real roach be gross . the rest of this movie rely strictly on really awful gray computer graphic animate bug . the cgi be so bad that when the bug attack one guy in particular it look like a gray liquid be cover him . these cgi roach move in perfect synchronicity and and they be dark gray . most roach be some shade of brown . the acting be horrible too . most of this movie have no bug at all because it be really a police procedural movie with bug . a detective be try to solve a homicide and and the brother of the victim of another homicide run into the police detective and they decide to work together . so most of the movie follow the typical police investigation format and and about every 30 45 minute someone get kill by the dark gray liquid which be suppose to be roach . the big mystery regard the bug be solve . there be supposedly an incredible technology which be discover to allow the control of roach and but the two bad guy who control the roach never show any control device or other gadget . they do not even talk to the bug . apparently and the bug work on esp . no control device be ever show and though many reference be make to the incredible amount of technology which the student bad guy be use . consider this represent at one point the hero be swat thousand of roach with his jacket . a few second later and he put the same jacket on without even look to make sure there be no bug on it . character regularly have spontaneous discussion while stand on the floor on top of thousand of man eat bug . by contrast and other character be engulf and eat in second by the same bug . it seem that sometimes the bug run at super speed to eat some people and but other time the dark gray bug just mill about or walk in place . the very end feature a very silly cgi a all the roach stick together to form a giant roach . of course and the police woman shoot her gun at the dark gray blob and nothing happens . the giant roach be kill off in another scene that be rip off from the terminator . there be several other scene that be rip off from other movie . they crawl lack any suspense or horror .
