I finished watching the first season of Ratched. It was a thriller! I stopped watching for a bit, then picked it up again. It was weird but I thought the acting was pretty good - Cynthia Nixon was good in her role as a trailblazing woman in 1948-1950, Sharon Stone was really good as a sinister tycoon (she had a Cruella DeVile quality and an over the top decadent, but subtlety creepy style) - and the sets and costumes were gorgeous.
I didn't like the gratuitous gore - and there was some in, probably, every episode. I had to turn my head or cover my eyes. If it's a thriller (rather than a horror - of which I am not a fan), and gruesome events are part of the story, I think TV and movie writers are capable of implying or having it narrated without showing us all the details. It's lazy of the writers, and unpleasant for the viewers, to show gory violence like that. I don't think it matches the rest of the effort put into the show, either.
I hope the set and costume designers win an award. That was worth seeing. I might not have watched the whole thing otherwise.
And, people are right, it doesn't have anything to do with One Flew Over the Cuckoos Nest. They could've called it anything else and it wouldn't have less to do with the movie or book. But I got over that. I realize it was just the writer of the series' imagination about what Nurse Ratched's life could've been like.
