I won't put any spoilers in here, so it's safe to read on, but, consequently, it's important to note that I won't be talking about anything near the end. Nothing spectacular happens whatsoever, but it's still no fun to hear about a narrative conclusion before you come to it. The film, overall, is about a man and hisson surviving in a world without the comforts you and I experience every day. It's about human intimacy and the practical experimentation of moral axioms that we've come to rely upon. It shows the challenges of the moral "good" and moral "evil." In short, it's a great apocalyptic film. Strong acting and good cinematography really support the script here. Anyway, you have my vote to see it, but I wouldn't bring the wife. It's the sortof tale that seems most applicable to the anthropological role of protector, which is often most psychologically suited for the fathers out there.
That's pretty much it. Conclusions are for papers. This is not a paper.
