Survival movie / drama. A post-apocalyptic film, where a sudden flash of the sun triggered the end of life on the planet. A few years later, the few survivors are trying to survive as best they can, as few animals are left, mostly some insects, and the vegetation has also been largely destroyed, many unfortunately become cannibals. A father and his son are also wanderers, but he has promised his son that they will remain "good" and will never become cannibals. A long journey of survival in a gray and desolate landscape throughout the film, where there are moral messages and ethical dilemmas about what one would do for survival and what limits one could keep. A very good and serious film, without silly elements or immoralities like others of the genre, tends to the dramatic element more and not to adventure like e.g. I am Legend. The excellent performances and the impeccable direction also give a realism. It is one of the best films in the category and definitely among the recommended ones of the genre.
