I am a big fan of the book
Inhabited Island is a great book and it could be awsome movie too. But for some reason, after seeing the trailers, I think it will not be the same as book.
It will take just main story and dialogs, but it will not have the same feeling.
The movie looks too Hollywoodish, a simple Michael Bay wannabe, trying to be too cool and popular.
I do not expect it to be a good movie, not even by comparison to the book, but as a movie itself.
See the official website with trailers, behind the scenes and photos:
