do not see this movie if you have read the book.

Rating: 1/10 (28 December 2007)

this movie is nothing like the novel written 53 years ago! if you have not read the book,then who cares go see it. you wont be disappointed because you have nothing to be disappointed about. the name of the title "I AM LEGEND" is the entire basis of the story which the movie completely ignores and changes. also it completely ignores the vampire creature as a non intelligent head banging freak. in the book they are a new civilization, some are completely infected which makes them vampire like and evil,but some are almost totally human. robert neville goes out to destroy the vampires thinking there is only the violent ones, but since they all sleep during the day, he kills all he can find including the semi human ones. in that sense he becomes a "legend"to these people as a ghost story that they tell to each other .
this movie also ignores the scientific explanations they give to the vampire myth. for instance, the sunlight would bother the infected because the virus made their skin very pale and would dehydrate them which would make them weak. another example would be that a chemical in garlic would irritate the virus thus having an effect on the infected. another would be that the virus made their blood congeal very rapidly thus u couldn't really kill them with bullets, you would have to drive something into their chest that was thick and hard , hence the wooden stake. and the last was the mirrors. they would always be disgusted with how they look now compared to what they used to look like so they did not like mirrors.none of this was explained in the movie.
it is almost like Hollywood re-wrote the novel and put it on the big screen thinking nobody had read the original. once again they are wrong thinking that all people are morons and don't read books. i am waiting for the day when Hollywood can actually make an accurate adaptation from a book into a movie. i am surprised that richard matheson is not freaking out about this, i am pretty sure he is still alive. this movie is a huge disappointment.
with the technology we have today in film making this could have been one of the best movies of the year. instead it is a "cgi drenched","post- apocalyptic", "run away from the zombies" pile of crap.only people that are die-hard will smith fans who have no knowledge of movies or books that just want to see special effects will like this film.
