first off, i recomend that anyone who hasn't read the book, to please do so. It's a great story, and probably equal to Dracula in terms of Vampire stories. When you read it, you'll understand why this film cannot be called "I Am Legend".
SPOILERS AHEAD! BEWARE!
The concept of survivors ruins the film, it destroys the point of calling it "I Am Legend". The vampires become the dominant civilization in the world. There is no room for Neville anymore. Concepts became reversed. Vampires are no longer the myth, man is. Man is no longer the real thing, Vampires are. The vampires fear Neville, and he cant exist in the world anymore.
human survivors destory that. The protesevich script(which apparently Goldsman is basing his script off) gets rid of the themes in the book. It becomes Night Of The Living Dead with Blade in it. That's not what the novel is.
and the Arnie/Ridely script is similar to the Protesevich script. The Protesevich script takes alot from the Arnie script. But where the Arnie script is better, it also destroys the themes in the book. Although, i could really see Arnold in the film.
But this new movie...it's just some rape of great literature. Sure, you have Superman, but he's built up on YEARS of different material. There is only ONE I Am Legend. I will not see this movie. I refuse. I'll stick to The Last Man On Earth.
