I Am Legend is a dark post-apocalyptic tale of loneliness, violence, sexual frustration and paranoia. The book begins medias res in a post-apocalyptic world where all the humans are vampires. It is a commentary on human nature and society rather than an entertaining and inspiring book about survival. Robert Neville, the main character does a pretty good job protecting himself and surviving daily attacks from vampires but he is also drinking himself to death. The reader is treated to Neville's deepest sexual anxieties and thoughts on society in general. Neville is also haunted by his past involving his wife and daughter which are revealed to us through flash-backs.
The book provides an in depth scientific explanation of how a human can turn into a vampire. I am not sure if I would have done all that in-depth research like Neville to get to the bottom of the vampire phenomenon. I think I would have simply hit the bottle and played some music. Frankly, I would have been scared to death.
The inner thoughts of the main character must have inspired Stephen King when he wrote The Stand. I think the book might also have inspired George.A.Romero when he made all those zombie movies. Even those are a commentary on society and how humans react in extraordinary situations.
The latest movie adaptation should have been called "Invasion of the Point-missers".
