I loved watching it, I havenโt read the book or watched the older Hitchcock movie, I only found out about them right after watching it. I donโt think you need any context from the book or other move, but I still enjoyed it!
I wasnโt 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 :)
