This is how it's done
Last Man on Earth is based on the same story as Will Smith's I Am Legend. But Last Man has a character that we really see the evolutions with. We see his daughter die slowly before his wife and the rest of the world. And we feel for him. Vincent Price played this beautifully. Watch out for the moment he finds a dog. Very emotional and heartfelt. There's also a little comedy. Win-win film.
