I've never read the book "The Boy in the Striped Pyjamas", so I just can't tell if it was a good adaptation to the screen. However, what i can tell about this movie is that the story was really surprising to me. When I started watching it, I just thought to myself "this is going to be just like all those movies in which a german build a beautiful friendship with a jew in the nazism period." So I prepared myself to see all those cliches that always appear in this kind of movie. But, as the movie continued, my certainties proved to be wrong. Bruno isn't a different kid, that believes all people are equal. He is just a bored kid that found the only companion he could in the circumstancies. As a kid, he doesn't really understand what is going on, so in the beginning he sees the whole and horrible true by childish eyes. As time goes by, he starts to wake up a little and see what's happening around him. By his friendship with the jew in the concentration camp, he doesn't understand why jews are treated so badly and why they are considered the enemy. The moment in which he betrayed his little friend is one of the saddest from the movie. It made me remember a moment like this in the "Kite Runner", but by a different point of view. To me, it showed that Bruno was just a kid, selfish and scared of being punished. The ending, however, was something really amazing and caused me the most strange impression, because we don't see an ending like that in this kind of movie, so full of truth and maybe serving as a metaphore to the entire nazism.
I recommend this movie to everyone and believe it was one of the most beautiful movies I've watched lately
