Something about the race warfare with cannibalism was rather disturbing. Also, the neutered first son. It was paranoid, IMO.
Let's talk about "The Stars, My Destination", and the perseverance of mid westerners to succeed under the most adverse conditions.
A.E.Van Vogt "World of Null A" was brilliant; but the E.E. Doc Smith saved many science dweebs from the world of boredom and other fates.
Not so, IMO as well. It took a stark look at what happens when socologically 'primitive' cultures gained control and had access to modern technology. Take a good look at that novel and think about the middle east today.
Take a loooooooooong look.
