Back in 2001, I wrote an essay for NCR on my experience reading some of the Left Behind book series. It turns out I wasn't nearly ambitious enough -- at least not compared to Fred Clark of the slacktivist blog. Clark, a progressive evangelical Christian, has since 2003 been systematically analyzing, scene by scene, the Left Behind novels, which purport to depict the coming end times in fictional form.
Clark's treatment is insightful and a great read; I look forward to seeing the latest installment pop up in my feed every Monday (or Tuesday -- he's not always prompt). If he can be said to have a basic thesis, it is that bad theology leads to bad art.
