i have just finished reading 'Brock Talon's' two books. In one of them, entitled Journey to God's House, pub. 2013, (pp.168-175),. he comments on how the WT's pictures of the post-armageddon world do not agree with their doctrines, namely that those who are physically resurrected will not marry/have children. As it is only JWs who survive the big A who can have children, the many pictures of (many) happy family groups are disputable.
I've never thought about this, but on going to the WT site, in one (2014) article, theyappear to be distancing themselves from the view that anyone physically resurrected will not marry/have children:

The article admits that the Bible does not give a direct answer (sheeesh! it's hardly a minor point!) and 'we will just have to wait and see' (you're in for a long wait!...).
As a postscript, I am surprised that with all the information he gives about himself, the person who wrote these books - giving himself the pseudonym 'Brock Talon', has not been identified! I enjoyed them although I have to admit that I found Penton's and Franz's books much more enlightening.
