I'm just about to edit and, I hope, post my review. I don't think I'd read the story, although I may have and forgotten it - I had a big Christie reading period when I was in my teens, I agree that it wasn't bad, but I did find it depressing. Some things I did expect to happen, partly because of the running length. I streamed it, I wouldn't say it struck me as blurry, but rather hazy, which I presumed was about making it atmospheric.
