The Day After Tomorrow is a fairly typical disaster movie, taking global warming and turning it on its head, to create a sudden super cooling effect on huge swathes of the northern hemisphere. Yes, I know, but there is an explanation given which sounds plausible enough if you try not to think about it. I guess any film that opens by plagiarising a Road Runner cartoon can't really be taken that seriously.
From there on, it really is just a typical disaster movie: the kids (led by Donnie Darko) trapped in New York, while Donnie's father treks through miles of snow to rescue them, accompanied by a couple of hardened adventurers, one of whom sacrifices himself for the sake of the mission. There's a shedload of effects, from hail-boulders to frozen helicopters crashing out of the sky. And, of course, there's all that snow - enough, apparently, to make the Statue of Liberty go all Planet of the Apes. And, of course, an incredibly cheesy finale in which the President of the USA humbly thanks the Third World nations for welcoming (presumably at gunpoint) all the refugees from the frozen Northern hemisphere.
For all that though, it's quite an enjoyable waste of a couple of hours, more so if you like effects heavy disaster movies, and despite its best efforts, it probably won't make you think too seriously about climate change (at least, not in the way five feet of river flowing through your house will).
Whether the conditions here at the moment are related to the real, actual effects of climate change, or just plain old freak weather, is not quite clear at the moment. What seems to be clear, though, is that it's not over yet.
Truth, they say, is stranger than fiction. Just, not quite as spectacular.
