Maybe best asked a question: was her story real? Was it all her imagination? Or was it supposed to be ambiguous to the viewer?
The problem I have with it is that, the way the story is told, it HAS to be real. It can’t be her imagination, which, of course, means it also can’t be ambiguous.
I think it would be a cooler story if it was written in a way that it could have been ambiguous at the end.
