Shades of Earth

FINALLY. I finally read this seemingly the endless book and the trilogy.
At the very, veeeery beginning, the author had really succeeded in hooking me with this new-planet-landing stuff. But later.. All I can remeber is my painful tries to wade through pages of a dull plot.
It took greater than a half of the book to return an interest to it.
You can say I could just give up and start to read something else. Actually, that's the way I usually follow. But in this case, after 2 of 3 trilogy books were left behind, an unfinished one would form a gestalt. I needed to know the end of the whole story. And the end turned out to be happy one (in case you had some doubts).
Despite predictable plot twists and characters, gaining zero my sympathy, my biggest gripe about that book was in other stuff.
This book just CAN'T be a science-fiction. Fiction? Yes. Science? Nope. At all. A science-fiction, despite of its fictional nature, is a genre that draws upon at least some physical laws and its limits.
The biggest pain in the neck for me was about all these ridiculous biological ideas (cosmonautics I even leave without attention). Genetic engineering doesn't work like THIS. Even in the far far away galaxy future. Just because it's break some limits. Modification of the entire human genome cannot be performed in such a short period of time. One injection and after a few seconds OMG YOU'RE A HYBRID NOW, NOT A HUMAN. Also, I should mention, that intellectual or anything-else human-upgrade cannot be occured in such a way. Intellect, an ability to rule the colony, charisma and other complex personality traits cannot be reprogrammed in one moment. These traits are not only genetically determined, they form also under suitable social circumstances.
All of these and different other ISSUES lead to my dissapointment in this trilogy. Sadly, but true.
