Query: Extremely inconsistent with the first two novels

The author decides to shift the tone of this novel to that of a social commentary on evil, and in the process makes the characters behave completely unrealistic. That would have been fine if this were a new book with unknown characters; however, the fact that the first two books attempted to use realism as their focus, this book becomes very disappointing. The ending is probably one of the worst endings in modern fiction if you take the first two books into account.
