It was OK. I wouldn't watch it again. There were definitely many loose ends that I would read the books for.
I don't mind Pierce at all in the role, Mamma Mia or otherwise. Maybe it was because I grew up on Remington Steele.
I find generally, when King's books are made into tv shows/movies the actors are not top of the line to begin with.
Anyway, glad I finally seen it, wouldn't watch it again.
