I'm about two thirds of the way through a proper read of this thing and, quite frankly, my criticisms still stand.
Granted, the Bishop sequences are pretty cool. There're some interesting conversations and it's pretty trippy to imagine Lance Henriksen talking to himself - yes, Fassbender did it as well, but with two different accents; it's established in A3 that both Bishop and Michael speak identically.
Sadly, when Bishop isn't onscreen, this book TANKS. Too much time is spent with needless secondary characters. One of them, Vietnamese smuggler Xuan Nguyen, seems to be a mouthpiece for Napper's undying luuuuurve for Hanoi. If anyone even coughs or sniffs, it reminds her of.... guess where? Why the f**k did she even leave? Yes, I know that the UPP moves people around regardless of how they feel, but a brief acknowledgment would have been nice.
The Colonial Marine characters are the same ol' archetypes we've seen a bazillion times before, although I do like the characterization of Marcel Apone, which is a rarity for pointless shoehorned character relations. He's pretty much how I would imagine Al Apone's brother to be like.
Also, the prose is clunky and there's a serious overreliance on onomatopoeia.
So, overall, not great.
