Query: For being so violent, you would expect it to at least be interesting

Usually violent books filled with sex (including rape, incest, and incestual rape) and gore are entertaining at least. But this one manages to be crude and disgusting while at the same time being excruciatingly boring and difficult to follow! It meanders from topic to topic with little consistency, and contradicts itself multiple times. It's like the author didn't even read the preceding parts! Also, there are terrible plot holes, even in the first couple chapters. There is a couple (one man and one woman) who are supposed to be the only people on earth, and they have two sons. Both sons find wives. Oops! Guess the author didn't think that one through very well... Some people swear by this story, but I really can't see the draw.
