After years of watching the series, from it's original first airing on TV back in the mid-1990s I've always said I wanted to read the book version. With the new series airing this year I decided to finally do it. There original series got about 70% of it and it got the major themes but the book has a lot more detail about side characters and events. It definitely goes further into the timeline than the original series too, although the new series covers a similar path. I can see why this is the highest rated King work. I've only read Mist, Cell, and now this. This was by far my favorite but perhaps that was because I had so much mental imagery to work with from my time watching the series. Worth the read for sure.
