Its a well known fact that Hollywood loves "Suspension of Disbelief" but this Movie Really Abuses the Privilege.
The Plot line for this most Amateurish Drivel, seems to be contrived only to appeal to the Brain dead Masses, who are never likely to see inside the pages of an Encyclopedia, and for whom Gun toting, weak dialogue spouting, Action heroes are the required Norm.
Once again It is yet another clichéd shindig that that sees a Hapless group of misfits and Hysterical Women pinned down in a remote location, by Over sized marauding Creatures intent on picking them off one by one, only to be saved at the last moment, more by luck than judgment, and then only to reinforce the Doctrine that the Good Ole US of A can repel anything given enough Firepower and Explosives.
