The other day I attended a preview screening of "The Road," the new film of Cormac McCarthy's post-apocalyptic 2006 novel of the same name.

It made for harrowing viewing, imagining a wasteland Earth from which, following an unspecified cataclysm, almost all life had disappeared. In that devastated environment, humans faced a terrible choice: Starve, or eat each other. It was a fun evening out.

There is clearly a morbid public appetite for destruction on the silver screen at the moment.
