Page-turning, but disappointing

I started reading this book with excitation (the announced masterpiece) and apprehension (size of the keypad). Unnecessary worry, the book is written so that each page requires immediate reading of the following, so it is quickly devoured without difficulty. The problem is taste quite bland. The introduction is yet extremely enticing: the characters we imagine "good" are led to an alliance with seemingly much "worse", promising a very ambiguous game. But the story soon takes a more monotonous round. Periodically, the efforts of "good" are undone by the actions of "evil", but they are not discouraged and you start to 200 pages ... Big disappointment.
