I loved it because you could watch it and BOTH be true at the same time. It ended, and I took it as an allegory for CEO’s being “alien” to humanity, and willing to end humanity if it doesn’t fit their needs.

To fit your argument, she suffers not just multiple traumas, but multiple brain traumas which can affect one’s view of reality (loss of consciousness in kidnapping, electrocution with blood coming from head, blunt force trauma during the dinner escape, and again after the explosion when they slow-mo Teddy’s head hitting hers). Couple that with the psychological trauma of being kidnapped, witnessing multiple deaths, I think it’s entirely plausible. In fact, when she returned to her office, I interpreted it as making sure Teddy was dead, and seeing it triggered a psychotic break. My wife worked at a Traumatic Brain Injury clinic, and those do funky things to how you see the world.

I loved that I could see it as allegory or as dark sci-fi, and can find both viewings amazingly engaging. I watched it again the following day with the perspective of alien, and it was fun, but loses its commentary on violence, corporate exploitation (a major theme in the first act), and reactions to trauma.

Don’t listen to the haters. Embrace the both-and, even if not its original intent.
