This could have been a good movie, the concept was there, however the most unbelievable situations arose that just killed the movie, like 1 all these scientists were supposed to believe the wold spray was out of reach and there was only 1, that they would have a scared scientists as the first point of contact that he cant do his job because he so scared, 2 that the neighbor transforms and his bullet proof vest still fits. 3 that they only have a few shot gun shells if they were that prepared. Just the most obvious and basic mistakes were made that even the most un skilled person would not make. To unbelievable, which sucks because again the plot was there.
