Not all of them are equal, as an article in The Boston Herald reminds us.
The article includes a list of must-see Stephen King adaptations.
I have one quibble with the list. The 1994 TV miniseries adaptation of The Stand (starring Molly Ringwald and Gary Sinese) is not included.
Yes, it aired 25 years ago. Nevertheless, that was a top-notch television adaptation of very complex and visually challenging piece.
