The book. Well I liked the book.
Problem is the book isn't for everyone. The book has an ultra conservative message, but not the religious based intolerance message of the deep south, or the anti big government message of the northern midwest, it's not even the racial based intolerance of the southern midwest. All of these are messages people associate with conservatism, but really those are not conservationism anymore than socialist nanny state is the ultimate liberal ideal.
I'm not really sure the message could appeal to anyone that was born after 1950. Because that is what it preaches, conformity, service, and patriotism with a mix of class based system that you are forced to work to attain. There are core values that are beat (sometimes literally) into people, and life is slightly devalued. I mean just take a second to think about what the bugs represent, a collective workforce, mindless and dangerous, it is supposed to be the opposite message, and it is a nearly unthinking evil in the book.
I really liked the first movie. It was never intended to be taken seriously. It was over the top action paired with a parody of the conservative message in the book. Think back on the movie, now imagine if all those tongue in cheek bits that where presented as "public service announcements" where presented in a way you where supposed to take seriously. That's how staying faithful to the book would be.
You can't tell any of this from the preview, so best of luck will be if it drops any social message and just has a bunch of power armored space marines killing some bugs.
