People's reviews.

The Boy in the Striped Pajamas explores the beauty of a child's innocence in a time of war, the common desire we all have for friendship, and the fences—both literal and figurative—that we must all navigate and choose whether or not to break down. -eNotes review.

My Auschwitz friend read the book at my urging. He wept, and begged me tell everyone that this book is not just a lie and not just a fairytale, but a profanation. No one may dare alter the truths of the Holocaust, no matter how noble his motives.

The Holocaust is simply too grim a subject for Grimm fairytales.- by Rabbi Benjamin Blech

As we can see many people thinks that yhis is a good book with a good intention to tell people the history of the holocaust and how this affect to a lot of people and also killed million of them and changed completely not only german and jewish lifes, also a lot of people´s lifes. 

We can also see that there are people who took this book as an insult because they remember the time that they spent in the holocaust or the time in the world war II and for them is an insult because they think that the author is makeing fun of them or took the situation just to write a book.
