It's not that Bad
Personally, I feel that every writer should have their own style - in this case, since it is written in a first person perspective, I believe that including abit of the character's thoughts and background (Choppy Sentences or whatever) might attract the reader better to the storyline, and of course, naturally, when you "know" more about a person/character, you would be alittle more inclined to reading it and understanding the storyline. I also find the Eco-Related theme gives a very good view on the author's 'Far-Thinking' perspective (For the future generations). The "Sexual Scene" (Though it was only a brief description once or twice) was more than fine, considering the fact the readers ARE HUMAN, and the very fact the human has sexual feelings might thrill them alittle; afterall, there weren't any direct elaboration at all. The so called "gory scenes" aren't that gory, mainly just chopping off his finger, of which there was not much elaboration (Constantly bleeding/Blood Squirting out/Finger felled onto floor wriggling). In fact, there wasn't even much talking about the cut-off finger in the other 2 books! Personally, I feel the Intro, body and climax extremely well written. However, David Klass could ahve spent more time to develop a better explanation for the characters appearing all of a sudden, and a better explanation on why they managed to come back in book 2. In a nutshell, the book is a worth reading book!
