Babylon The Great Has Fallen: God's Kingdom Rules! was silly but I didn't mind it so much. Despite its dryness, you could sense the passion of ole' Fred. He knew where he was, what he was doing and where he was going (Or so he thought) --completely and utterly convinced of his own importance and the importance of the organization that he belonged to.
However In JW society, books aren't rated, critiqued or reviewed as to quality in any way whatsoever. Just as it was with Rutherford before him, Fred's books got steadily worse as he delined physically. Rutherford reached a "low" with the book, Children and Fred reached it with Paradise Restored to Mankind By Theocracy. Both were just terrible.
Children was before my time, so my vote goes to the latter of the two. --Fred's last attempt to confuse everyone.
