I enjoyed it up through the 5th book (and there's a later, interstitial book I also enjoyed). I don't necessarily regret reading books 6 and 7 because I wanted to know how it ended, but on the other hand, I do kind of regret reading them because 6 had some awful and tedious stuff in it (it uses a trope I am so so so exhausted of and the eventual payoff is not worth the awfulness of getting there at all), and I also hated the ending of 7. Not to mention the other thing King does that I found super irritating. (Note: I am not a big reader of his books? So some stuff was lost on me.)
