The Aliens died because of the earths bacteries; "the moment the invaders arrived, breathed our air, ate, and drank, they were doomed. They were undone, destroyed after all of man's weapons and devices had failed, by the tiniest creatures that God in his wisdom put upon this earth. By the toll of a billion deaths man had earned his immunity, his right to survive among this planet's infinite organisms. And that right is our's against all challenges, for neither do man live, nor die, in vain." I liked the movie alot, but can some1 explain what the heck were the red vines and what for? :?
