Let me start by saying that the story wasn't that bad, and with bad I mean a predictable, stupid plot with dull and even more stupid characters, absolutely not. They were both in fact well thought and articulated. 
 Then why, you might ask, is you rating so low? Simple: I felt nothing while reading it. No empathy, no fear, no excitement... nothing. It was almost as if I were reading a textbook for school: knowing that I had to finish it, but without feeling involved because, well, it's always a textbook. 
 I didn't manage to create that link between the characters and me as I've done with other books before, I didn't even care if they survived or not! 
 I'm afraid the main problem that prevented me from enjoying the book was the writing style: though using a first person narrator should have made the story more thrilling, "nearer" to the reader, there was just no personality in it, almost a mere description of facts. The parts set in the Wood where really great because you could perceive the tension, the fear rippling in the air, the threats hidden behind the trees and ready to strike; in most of the remaining parts, though, no emotion was conveyed, and as a consequence even the characters seemed flatter than how they actually are. 
 Such a pity that a story with a good potential got ruined by this!
