Like everybody, I was a kid once, so I of course have found memories of family friendly movies. The NeverEnding Story, The Land Before Time, All Dogs Go To Heaven, etc. For me, part of the greatness of the films listed above are that they don't hold back on what life really is. There is loss in life, there is darkness, so these films seem to work as sort of a guide to get through that, while also being fun to watch in their own right. I feel that most family films made these days (and most of the ones made in the old days as well, the films I mentioned are more the exception than the rule) lack any real depth that adults and children can relate to (though Zootopia and Inside Out were both great films you should check out immediately if you haven't already). That being said, I'm happy to report that The Jungle Book did not fall into that latter category, it does in fact face life's joys and sadness head on, and sends the message that with friends, family, and a little courage you can persevere.
As far as the technical aspects of the film, it looks great, the voice acting is on target, and the leading performance by new comer Neel Sethi is amazing in how natural and believable it feels. So if you're looking for a well made family friendly movie that actually has something to say, put The Jungle Book on your list.
