Much, much better than the movie of the same name, although considering how awful the movie is, that doesn't really give a good idea of the quality of Matheson's novella. The movie is about goofy looking CGI monsters that roar at the Fresh Prince. The novella is about vampires and the efforts of the last man on Earth (thankfully not the Fresh Prince) to stop them. While the movie focuses on the conflict between the Fresh Prince and scary things that jump out of nowhere and roar, the novella focuses more with the internal conflicts that plague the last man on Earth. The main character has to deal with feelings of boredom, depression, hopelessness, and a passionate zeal for "solving" the vampire problem. The movie wants you to be scared of what's outside the house trying to get in, whereas the novella makes it clear that the real terror is the isolation of being the last man on Earth, which makes the novella infinitely more interesting and enjoyable than the movie.
