Either a brilliant social experiment or the best way out for both of them
Hear me out. Wild personal theory/best way out for both parties.
What if this was a massive social experiment about what DV/abuse looks like? How outside parties can be manipulated, the role of misogyny, the use of social isolation. How DARVO play out in real time, and how many times there no clear cut victim/abuser. Add to it how easily we can be manipulated by media of all forms, and the role of sensationalism. Now play it out in the back drop of a movie specifically about DV. What a way to draw attention to a difficult and nuanced topic.
And if not... BL, JB you're welcome for you way out with all hands clean.
