watching : "I am Legend"

My favorite genres of movies are physiological thrillers and action movies. The movie that I just finished watching was “I am legend”. This movie was packed with action and reality about the earth on a new level. The setting of the movie was New York about four years late, when a biological agent turns bad. There is a vaccine in 2009 that’s developed claiming it’s a cure for cancer. This is injected into a few people and the vaccine becomes an airborne virus that cause homo-sapiens and animals to bevelope rabies. This agent (will smith) plays the super human in the movie that stays in new York to fight off the ravaged people and find a cure. He is immune to the airborne virus and tries to use his blood for the cure. Over the course of his research he gets in contact with the diseased people and fights them off at in the day. When his beloved dog dies he goes after them at night, when they are most active. Ths is a mistake, but amazingly he is rescued by two survivors whom escape and the hero dies in the end.
This movie was one of the better ones I’ve seen in a while. To think that this could never happen but on the other hand some parallels to it. This could be a reality if genetic engineering kept taking place in finding and modifying the human genome.
