I loved watching it, I haven’t read the book or watched the older Hitchcock movie, I only found out about them right after watching it. I don’t think you need any context from the book or other move, but I still enjoyed it!
I wasn’t sure which direction it was going in at times, and that kept it interesting. I had to pause halfway through (because life gets in the way), but the movie was stuck at the back of my mind the time I was gone, if that means anything :)
