Eh it comes off as a corny and flat depiction of people who might otherwise be interesting. Romantic, but not a depiction of believable humans. And the problem certainly ain't the actors.
I've never read the book, but perhaps this criticism applies to the book as well. King certainly has a tendency to push fetishized characteristics that take the place of earnest characterization. This is certainly true of the Stand, the Dark Tower series, the Shining, Insomnia, Green Mile, and probably many others of his works. This is not an original take.

I like the movie, it's one of my favourite films of all time, and I am sorry you feel I and a large contingent of people are misguided because they have a different opinion than yours or your favourite critic's.
I have rewatched it in the past 6 months BTW.
