I thought this was a really interesting antidote to all of the mow-hawked and black leather-wearing silliness that seems to occur after the apocalypse in every other movie of this type. There are no marauding gangs of motorbike riders here. The innocence and ignorance of the titular characters is alarming enough; seeing them foolishly expend all of their wooden matches because its amusing to them before they attempt to cross what looks like the Cascade Mountain range is painful to watch! I happen to think that if anyone ever did survive an Extinction Level Event,they might behave something like Glen and Randa; what has destroyed the world is never explained; no mention of nuclear war is made and when the characters stand at what is obviously the west coast of either Oregon or California and explain that ..."about ten miles that way there used to be a city called Boise!" you realize that whatever happened, it was massive;nuclear warheads don't re-shape the coastline! The found sets--wrecked cars sunk in sand, mobile homes that look as if Godzilla stomped on them, a rusty derailed train half submerged in a river--lend a sense of surrealistic realism to the film, if that makes any sense. This movie moves at a slow pace but i was captivated by it, wondering what would happen next. I think one of the most powerful aspects of this film is the fact that there are NO characters who provide a sense of sanity and strength; all of the older characters seem to have been driven into a sort of semi-schizophrenic absent-mindedness by whatever it was that slammed the crap out of the old civilization and the 2 youngsters seem so ignorant and unaware of the inherent dangers of their travels that you seriously worry about their safety as they tramp barefooted thru the mountains, across deserts, etc etc. I would recommend this film as an example of what can still be done with the post-apocalyptic genre. This one was a breath of fresh air.
