How I Live Now. Post-apocalyptic (World War III? Nuclear bomb in London? Terrorists? Never fully explained but it's unimportant) teen film with young lovers separated in the post bomb kerfuffle. She treks back to find him. I've just looked at some reviews, and it seems many reviewers didn't like the romance-y stuff. I would say I borderline ignored it, though not wilfully - I was just caught up in the post-apocalyptic, wartime stuff, and the aloneness of it, and the incredible scenery. It's set in England and the majority of it takes place outdoors on hills and in forests and it just looks absolutely beautiful. I suppose if I really think about it, it's fairly standard post-apocalyptic stuff as well, but I like that, so I guess it gets a bit of a pass from me. There are some blind alleys in the plot as well, and things that happen that aren't at all well developed or explained, which was a shame.
Not great, but wonderful to look at, and if you like post-apocalyptic stuff you might enjoy it.
