If you've seen any "End of the World as We Know It" movies before then you'll be overjoyed how this one falls right in those well worn directorial footsteps. Small group of "survivors" start disappearing one by one because they are unbelievably stupid at all the wrong moments. At least we'll all know what NOT to do if there is ever a real Doomsday as in DON'T open doors to strangers, DON'T give the crazy guy a gun, or think playing Big Brother in a house full of morons is a recipe for success. Did this film ripoff other previous versions of Last Man Standing? Of course. It's Hollywood, where originality died a long time ago.
