Oops, I only just saw this lol sorry.
I mean, if it’s “Possession” we’re talking about, I covered it pretty well in that column what the director was going through. A divorce, the need for control, feeling like you have to keep the facade of a perfect family going. But outside of that? Not particularly, especially in regards to plot. I understand that the idea of the doppleganger was finding the better versions of both of themselves - whether made by hand or the teacher at the school - in order to raise their child, but that didn’t make it any clearer, or better, for what it’s worth.
Frankly, I was so offended that I wasted time watching it, despite how fascinating it was in light of its awfulness, that I really didn’t want to look much deeper into it beyond what was necessary in order to write that piece lmao
