take a b movie idea and put it together with clever cinematography and good acting and a reasonable budget and and you will have one of the fine movie of this genre ever make . peter weller basically do a one man job on this movie . i have a new found respect for him after this . in this move he play a straight arrow guy and generally normal and like to research before make a move . a pretty normal guy however and in this movie we get to enjoy the breakdown of his be while he have to come to term with the force of nature ( or the super natural or xeno nature ) . for everyone who have ever get frustrate by a hellish problem or work in a job that should have more cathartic release and see this movie .
