We'll just have to agree to disagree. I find when everything is changed, it's not an adaptation, it's a way to capitalize on a popular book title.
But it's not the same main character, tey are not even close. Only their situation is simlar. There are a dozen zombie movies with the same premise. I'm not damning it for it's differences. There are too many differences to even compare he book to the film. I didn't think it remotely captured anything from the book so I judge it as a stand alone movie. It was fine until the woman showed up.
Lots of spoilers
But everything wasnt changed it was adapted. I see plenty of parallels.
- Focus was put on finding a cure which was just one part of the book
- Nevilles glimmer of hope was a dog who just happened to have a closer realtionship with him in the movie and both met theirdoom by the hands of the creatures.
- The creatures had a sense of development but it was not capitalized on. But the Alpha male character obviously made it personal with Neville because the women was obviously his mate.
- The woman character in the book was split into two characters: the creature and the women but then diverted to much from the concept and is the only change i cant live with
- instead of visiting his wifes grave everyonce and awhile he is plagues by her death in his dreams. And since I always thought that because he didnt burn the body in the book that he caused the widespread outbreak. He still has a direct line to the virus being hired to stop it.
Changing setting and occupation of Neville are the most divergent changes before the woman was introduced, none of which have any real bearing on the rest of the story. The tone was very well done. I thought Will Smith was very convincing of his fear and emotion. The scene in the creature nest, the scene when he threatens "Frank", where he kills Sam, and where he breaks down in front of the adult film mannequin, were all very raw emotional scenes.
Im not saying it couldnt be adapted better but there are certainly parallels between the two. These changes are sometimes needed because film is a different medium than books. It requires more showing then telling. Thats why the dog had more focus and the mannequins were included so that the actor could have someone to interact with. They did the same with Cast Away.
I would have liked for the creatures be more human adding the former best friend character and the hunting of the creatures during the day. The CGI was awful, I dont know why but when i read the book i saw the Skull Island natives from Jacksons King Kong.
