I just finished reading the book this morning, and wholly agree with Hick's review
It's an amazing book, and I highly recommend it for those who find the movie's lack of explanations of the characters motivations aggravating. The book does put most of the issues with the logic to rest.
Some parts that are still unaddressed would be questions like was that planet the Engineers' home world?
Why did the mutaphage cause the humans to develop neomorphs, but the engineers just seem to petrify where they stand? In the movie we can see that their bodies do start to melt and warp ala The Thing style, but shouldn't we expect all the hosts to have neomorphs appearing everywhere?
Also, in the sequence where the second facehugger was attacking the Sgt, it was written that Lope got an arm between the tube and his mouth, so there was no impregnation taking place at all. Thus, how did the alien that burst out of him on the ship came about? Did David/Wathers slip him something while on board? In that case, why not slip all the members something? He still had 3 mini eggs at the end.
And unfortunately, the family dynamics emotion issue is still lacking. I still found myself asking around the middle of the book who was whose spouse, especially the 'soldiers' contingent, as there was only 1 female but 5 guys. Did that mean there were 2 gay couples among the security team? None of the team besides the Sgt seemed to have any emotion about their other halves buying the farm, so it was really hard to tell and kinda degraded the whole 'ship made up of couples to generate emotional tension' concept, even in novel form. It seems likely that the original script just didn't bother with it beyond the more prominent characters, and no one caught on.
Possibly we can find the answers to the engineer questions in the tie in novel, so I'm looking forward to that.
