Overall, it was a disappointment. I felt like it was advertised to be a piece that was going to connect a lot of the Castle Rock stories, and even the title sequence references that idea. But this is a stand alone story, that mentions places and familiar names in Castle Rock, but doesn't connect anything. Sure, there is good ol' Shawshank and the Mellow Tiger, and you have Jackie Torrance and Sheriff Pangborn and several references to Cujo, but that's all they are - references. As a long time Stephen King fan, I was looking for so much more.
In addition, this story isn't very good, and is very slow. The bright spots are Sissy Spacek's amazing acting (especially in the episode "The Queen"), and a nice, grumpy turn by Scott Glenn. But that's where it stops. The rest of the cast is just so-so. It's like a sports team: the money was spent on two awesome players, and the rest of the roster is just okay. Those two are nice to have, but the team isn't going to succeed. That's how I feel about this series. Not a success.
