If you've read the book, the film is a disgrace

Rating: 1/10 (8 January 2019)

Stopped watching less than 5 minutes in - why?
Sandra Bullock could partially see through her blindfold - thereby destroying one of the major premises of the story. I have also heard of other sledgehammering of the original story.
The "monsters" don't have to be explained - that is the freaking point!
This could have been a great film.
