Pros: Intimate, human, historical, tragic, incredible
Cons: Years in an attic may seem monotonous to some (not me).
This is a document that depicts the personality of Anne, who is a clever, complex and not completely likeable person. All of these traits the reader experiences reiterate the fact that this is a private diary by a real human being, with depth that no fiction could ever mimic.
The reader has the strange viewpoint of Kitty, Anne's journal and closest friend. Though this may suggest a great vantage point to gauge the true personality of a person, it really only conveys the side of her that noone else in the world experienced when she was alive - the secret, quiet, loving, self-analyzing person that her family never understood and she deliberately didn't let anyone experience. This is highly ironic seeing as the person she states was her facade that everyone saw was entirely the opposite; opinionated, confident and loud, though she wished she could express her inner self and be taken seriously. I think she would be pleased to know that millions of people now understand her secret personality thanks to her diary.
I found that I could relate to Anne in almost every aspect of her personality and I wonder if many others could also.
This is unique, and it should be read by everyone.
