I bought Under The Dome when it was part of those Amazon vs. Walmart low-price wars; I think I got it for five bucks with free shipping. I never finished it, though; at over 1,000 pages in hardback, it's a bit difficult to hold up in bed, which is where I do my serious reading, but more problematically, it was a paragon of a trend that ultimately makes Stephen King a very frustrating author for me to read. His habit of cleanly dividing the world between the forces of the unrelentingly evil assholes and white knights who can do no wrong has always seemed to be the most fantastic aspects of his books; the real world certainly has awful people in it, and some very nice ones, but King's efforts to place everyone into good or evil tribes has always struck me as frustratingly simplistic.
Under The Dome was one of his more indulgent books in that sense, perhaps coming in second only after The Stand among those that I've read. There's no real conflict for the reader; it's not like you're ever going to choose to be sympathetic to the rapist/murderer/meth dealer faction in the novel. It wound up coming across as a fairy tale, to me, which is too bad, considering the rest of the ideas in it were pretty interesting: a small town gets caught inside an impermeable, invisible force field, preventing anyone from going in or out. No one knows precisely what the force field consists of, no one can break through it, and tensions begin running high. It'd be a fine idea for a novella, but of course King has to make it into a battle between Ultimate Good and Ultimate Evil, as the town's deputy mayor goes crazy and starts to treat the area under the dome as his own personal fiefdom, recruiting his murderous son and his friends as a privatized police force, etc., etc.
The novel, of course, sold millions of copies (again: five dollars), and like everything else that King creates, is now going to come to a screen near you. Interestingly, though, the plans for it are apparently for a series, not a mini-series. Showtime announced today that King and his old collaborator Steven Spielberg are going to work with Dreamworks TV to produce an on-going series based on the book, which I presume would start airing sometime next year if they're announcing it now.
It's curious that they're announcing this as a series instead of a mini-series, but I suppose they can string along the people in the town for as long as they like before getting to the meatier revelations at the end of the novel, or simply come up with a new "ending" as they see fit. The plot could wind up being a bit reminiscent of the early parts of Jericho, should the producers decide to go that route, but knowing the track record of King adaptations, I'd expect a goodly amount of cheese on your plate. Which makes me think: has any other King novel ever been adapted as an ongoing series? There've been plenty of movies and mini-series, but my mind is blanking.
