I was watching HBO last weekend and this was the movie that was showing that time. I’ve watched this already before, I’m not sure though if I watched it in a movie house or also on HBO or DVD but I decided to watch it again. There’s nothing else to watch anyway on the television. And besides, it’s Will Smith!!
It was a movie about a cure that was made for cancer (altered measles virus). Unfortunately this cure mutated into a lethal airborne strain. It infected 90% of humanity. The remaining uninfected people are either being hunted/killed or committed suicide.
Will’s character (Neville) is left as the last healthy person in New York City. His family was killed in an evacuation mission when the helicopter exploded. 
Neville spents his days with his dog (Sam) & experiments on the cure of this disease as well as finding survivors. One day, he sets out a trap to capture an infected woman to test the cure that he has made. The leader of the infected group saw this and try to attack him but since infected people are intolerant of sunlight & uv rays, Neville was able to escape.
One time, Neville was victimized by a trap created by the infected group, they set out infected dogs to attack Neville and Sam. After Sam and Neville was able to kill the dogs and get back to the laboratory, and try to cure Sam unfortunately, he was infected with the disease and try to attack Neville, poor Neville, all he can do is strangle his dog and bury him… now he’s totally alone… with this.. Neville try to seek revenge by attacking the infected group, I guess also his way of giving up as he’s all alone now..
Fortunately, he was saved by a woman and a boy who was on their way to a rescue camp. They all went back to Neville’s laboratory. The infected group found a way to Neville’s laboratory and starts to attack them. Then, Neville noticed that the cure he made was working! With this, he took a sample and gave it to the woman and asked her that this is the purpose why they met and let them escape.
Neville sacrificed his own life and put up a bomb killing him and the infected group. The woman & boy was able to escape and arrive at the rescue camp and gave the cure that Neville made. With this, he became a legend.
Nice, meaningful.. I notice that Will Smith movies are really worth watching. This is one of them 
My rating for I am Legend: 4 out of 5 stars.
will smith movies are always good.
