I've read a lot of comments about this movie, but I still don't understand why many people don't like the ending. How does it spoil the impression of this movie? How is it stupid? I totally disagree with that. As well as with the fact that it's a movie about aliens, or how not to go crazy when meeting them. Didn't anyone see the main idea in this picture, and if you understand it, you can understand the end? Did no one think about why the priest is the center of the picture? And not a farmer, a tractor driver or a guy from the local machine shop?
Aliens with their invasion are not the basis of the movie. And even the people with whom all this happened, or rather one of them, are not just villagers with their skeletons in their closets.
This picture has a certain religious meaning. And the protagonist here is a priest chosen for a reason. This movie tells us about a man who disbelieved in the existence of God, even being a priest, after the death of his wife. And how he and his family try to save themselves from the aliens by their own efforts, without faith. How he tried to make it on his own, without His help. The aliens here are essentially the personification of a threat, a global threat. It should also be noted here that religion does not recognize the existence of extraterrestrial civilizations, but considers aliens to be demons, devils, and a manifestation of demonism. Religious overtones again, don't you notice? Demons versus priest, to put it crudely.
And the ending in this movie is just right, it puts a solid, fat point at the end of the formulation of the main idea of the movie - something like “everything happens as it should” or “God's ways are inexplicable”, if you want. Everything is clear for those who have correctly understood what the movie is about.
