Not sure why people gave it a low grade. The movie is as decent a horror movie as many out there. The concept of a wild, untamed, human being found in a civilized setting in the 21st century is weird. I could understand if this happened in the Amazonia. But, let's assume it is possible. We would all look at that being as a savage one, and, likewise, we would be very strange to that being.
How do we adapt to circumstances which are completely new to us? What is the role of God in a modern society? Are we understood if we are complete outsiders somewhere? All of these questions could apply in a broader sense to the world we live in today. Many of us have felt as outsiders sometimes somewhere in our lives, and we learned to adapt, to change. When we go to a new school, or start a life in a new city or country. Sometimes we get accepted, sometimes not.
But, enough of going into philosophy. Just watch the movie. It is completely okay to watch and is not a waste of time.
Although it is a third sequel, it can be watched on its own.
