I do think this book have a lot more relatable human substance in it than the movie. A bit more gothic horror which was pleasant in some ways. But I can't help it but I want to burn the book whenever the book went into detail about the science stuff surrounding the whole plague. Neville had this 'studies' on Vampirism as one of his past time. He often go into houses and experiment on vampire comatose as a past time. He's not completely wrong with his science-speak but to me it felt like the character is someone with basic high school level laboratory skills who suddenly became a mad scientist by the library books he read. He even self-learn how to use a microscope but didn't even know how to use staining methods in microscopic identification. He just assume he saw bacillus bacteria and immediately name it as Vampire bacteria. Except that even harmless bacteria can have bacillus shapes. He even have checklists of his findings about how he think these bacteria work but totally ignore the physiology and pathophysiology of the disease itself and instead preoccupied with his observations based on his superstitions. Also he claimed that he CREATED vampirism antibiotics and tested it and that is where I drew a line. In this book, the use of science is just an accessory to the novel to allow a more deus ex machina revelations in the end. 
 It was a short book and I just listen through the audiobook throughout the night while playing 2048 puzzle. Neville isn't a scientist before the vampirism plague hit the world. He constantly refer his scientific skills and inborn skills inherited by his father rather than having some actual experiences. He did a lot of newbie trial and error that a lot of what he know came from reading textbooks rather than practical books. Maybe that kind of exploration was intriguing to some but to me it did get predictable in the end. I do prefer Will Smith's Neville who is a more flesh out and tone down realistic legit scientist version than this amateur. I guess, I ruined the book on my own just by having research background. It was poorly done but I can sympathise since the author probably learn everything by the library books he read. Now this reminded me of the speculative fiction essay I have to write.
