My favorite book in the world, somewhat ironically, is Good Omens by Terry Pratchett and Neil Gaiman. It begins, more or less, with the birth of the Antichrist, and then skips ahead to the End Days, when a lower-level demon and a disgraced angel decide they really don't want the world to end after all, and wotk together to eff up God's Ineffable Plan. It is, as you might imagine, not entirely serious. (To the contrary, it's funny as hell.)
There is, of course, a more well-known series of books about the End Days, but I'd never had any interest in reading them. (I did leaf through one volume of Left Behind in a bookstore, but the prose was about on a par with L. Ron Hubbard's Mission: Earth series. And Hubbard at his best made Edward Bulwer-Lytton shine like William Shakespeare by comparison.)
But the other day I stumbled upon the Slacktivist blog, run by a guy named Fred Clark who, among other things, decided to analyze the first Left Behind novel in detail, a few pages at a time. He started in 2003, and is now nearly finished going through what he describes as the Worst Novel Ever Written (a charitably nonscatological epithet, in my opinion). His analysis is everything the book itself is not: well written (save for a few spurious apostrophes), intelligent, insightful and entertaining.
The most amusing thing about his analysis, at least to me, is that Clark himself is an evangelical Christian, and throughout the entire novel is continually pointing out scriptural and doctrinal errors in the authors' "literal interpretation of Biblical events", in addition to the horrible writing, unrealistic characters and absurd plot points. Seriously, if an evangelical Christian is pointing out how feculent Left Behind is, it's a pretty damned shitty novel.
