TBH, I didn't watch the movie myself but my 2 kids did. In hindsight, I should have gone with them. It turns out this has a DEEP message for children and young adults. It was my 11 year old who said "This was a movie about the Second World War 2.0" He realised there were many parallels, and basically the movie is saying that hunting people for no real reason, just because you don't like them is never a good idea. Of course this is a feel good movie so it will end well. The last hidden meaning it at the end of the movie and makes perfect sense.
The message has been laid on thickly, but that's a good thing when you are showing such a movie to children, who might not get a more subtle reference, especially because WWII is so far away for them. For me, I have met and talked to people who were there and could talk about it from experience. Children these days hardly get this opportunity anymore and it makes me happy that they learn about the atrocities in a child friendly way.
I was a little shocked when I heard it was about this heavy topic, but given that it was brought so well AND that my son understood the reference while watching it makes me give it this generous rating.Kudos to all the people involved in making it.
