DREAMCATCHER, the book, is somewhat of a sequel to IT and TOMMYKNOCKERS, and is the most old-school Steve King horror book since DESPERATION. It is not as great as original era King but it is not as utter shit as much of King's output in the past 20+ years.
The movie, of course, is nowhere near as good as the book, but since the book is not incredibly great per se, but rather just an old time King nostalgia trip, the movie lives up to that in a sense. Most King movies suck, so why shouldn't this one too? But to be fair DREAMCATCHER is better than pretty much every Mick Garris movie. The worst thing about it is the shitty CGI
