Stephen King's epic plague-Armageddon evil-against-good horror soap is extremely faithful to the book even if has some over-the-top scenes, especially by Matt Frewer. It is a production that looks good, especially during it's first episode when the plague hits U.S. and we get to see a lot of bodies and an abandoned New York and the ensemble is impressive. The ending is plagued with the same problems as in the book.
One of my very favorite fiction books of all time was turned into one of the worst film adaptions of all time, a watered down TV movie that is so sanctimonious that it could have been produced for the Trinity Broadcasting Network. Apparently there are plans to create a new theatrical version, and I hope they do it right this time. Rule #1 of a Stephen King film adaption: keep King as far away from it as possible.
