I'm a Legend with Will Smith

I'm a legend is an american film by Francis lawrence, in 2007.
In 2009 a scientist find a cure for the cancer, all people enjoy because 40 sick patient be cured. But people didn't enjoy long time, the cure had a 2nd effect. The virus propageted and kill the most weakest and the other mutate to monster. Will Smith was the captain of police, he try to protect his family but they died in a helicopter accident. After this, he just wanted to stay on his city to resound the problem. But at one moment, he was the last man of the city, and he live with his dog and all the monster. The virus propageted to dog too. All the monster ( dog and monster ) can't move the day because the light kill them, but the night, they just kill all of what they see. And at one moment of the film, 2 person come to the city ( will smith say a message on radio all the day for survivors ) to save him at a moment, the moment where he want to suicide because of one reason. ( i don't say it for spoil you).
I really like this film because he show us the brave and determination to a man can have.
If you didn't see him, i really suggest to you.
