I have yet to read the book, but I can say that this movie is wonderful. This modern day teenager is taken back into the past to the time of the Holocaust, taken to a Nazi death camp, and experiences what really happened. I dont think many of us truly realized what it meant to be a Jew back then. Jews were treated as 'pets' in those camps, being branded, 'owned', and forced to work, which basically makes them slaves. I knew about the Holocaust before this movie, and I knew it was so terrible, but the reality of it never really hit me until this movie. But now I think I understand so much more. And I'm only 13. It shows the Jews when they first get to the camp, when they are forced to take off their clothes, put on other clothes which include a special coat with the Star or David on it, have their hair cut off, and get branded with a number on their arm for identification. And then we see how they lived, what they feared, and worst of all, how they died. I'd have to say the ending is what really hit me the most. I wont tell you what happened at the ending, but I will say, if you watch this movie with all your concentration and heart, you will feel a feeling you've probably never experienced, because you've probably never felt the real pain of torture and horror. And that it what this movie expresses.
