consider this movie be do with a no name cast the acting be top notch . the actor should be give award for the quality of act and i do not see any of the stereotypical woman panic or war hero run around with shotgun spout clichés . they pick some quality for the movie and i really hope to see the cast go on to big and good thing . consider this movie be low budget the effect and make up and scene be very well do . the gritty city and the typical way people tune out the warning sign because every day you hear a siren . where this movie fail be some plot hole and reality check . while they never develop a background into 3 of the main character and there be heavy indicator that they share history . it leave you with the feeling they should have fill u in on the connection . in order to view a horror movie we must be able to turn off that reality check in our mind tell u that this can not happen . but this movie fail to give the common viewer an explanation for the spread of the infestation . not a great horror movie but definitely a good one to watch .
