No, no you are not.

Rating: 1/10 (23 December 2007)

Whenever a book is adapted into a film, there is some dread. Some deviations from the source material are unavoidable, but clever scripting and a good cast can, in some instances, still make a good film. This is not one of those instances.
The charmingly blue-collar Robert Neville is gone, replaced with soldier/scientist Will Smith. The virus, rather than creating vampires, apparently turns people into poorly-textured CGI abominations. Gone even is the nightly terror of having the vampires standing about on his lawn, taunting him. Despite being able to smell blood from a great distance off and move like only modern CGI monsters can, the vampires "don't know where he lives". As a matter of fact, the only holdovers from the book are the name of the character and the idea of a virus turning people into something. It is, in that sense, very similar to the "work" the director did on "Constantine (2005)".
Now, you may wonder if the film is worthwhile if you haven't read the book, and thus have nothing for it to spoil. The answer is ... still a resounding no. If you haven't read the book, this film will simply insult your intelligence and waste your time rather than insulting your intelligence, wasting your time, and butchering a great read.
There isn't enough time or prose to explain all the reasons why the movie-going public shouldn't pay to see this utter dreck. I implore you to skip it, for the sake of your mind and well-being. This film may, indeed, become a legend, but only in the sense that a great many people paid a shocking amount of money to see something so indescribably wretched.
