I watched this recently on Halloween night, and it’s genuinely fantastic despite its age. I'm planning to watch it again soon because you have to be very attentive to grasp what's going on and keep up with the plot. It seems like watching it a second time would help clarify things and make everything fall into place better. The entire viewing felt like constantly being misled; just when I thought I understood, something else would emerge that proved my assumptions incorrect. Those unexpected developments were wonderful, as was the unsettling feeling of uncertainty – is this actually occurring? Is she truly performing her role, or is it simply a mental illusion?
