I'd say when the mother was shown yelling while the daughter is passing, one might suppose that something happens to the daughter's psyche as it is in transition going one place and the mother is calling it back to another. So, realistically something weird could happen but this movie shows that the key to understanding this "delicate" situation is to just be patient, wait, and don't have anymore traumas and everything just may straighten itself out just as it did in this movie and that I like very much about this movie. It was realized sensibly eventually that a choice had to be made and the choice to live both personas (both presence of minds/consciousness) as a natural course and let the mind figure out how things will go...well, I liked that part.
I can see why some peope had a problem with David Duchovny's performance; it was actually unnerving to me at times. Is it realitic for a guy to be so horny when his daughter is so ill? Okay, I'll grant the script its take on this situation. Mourning comes in stages and it is very difficult for a husband who loses a wife he loves but the script should have been written to show him in mourning stages but then I grant the script what it did suppose that the husband did go into mourning for his wife once his daughter was fixed in her mind. So okay. I think that might have been a normal course for some guys but not for others. Some fathers would have taken their daughter to their sister's or grandmother or aunt, some female in the family and that would have been it. He would have entered his mourning stages even though his wife's "mind" was in his daughter's body. But this way is a possible way to do it so that everybody ends up SLOWLY growing into the new reality to avoid more shock and trauma. The point is: the body often heals itself, including the mind.
But I did have a problem with a mom who could stop herself from using drugs like the daughter and having sex with her boyfriends but she couldn't stop her self from wanting to have sex with her daughter's father. That was out of place with the mom we were shown. But then, again, I guess I have to allow the script to allow everybody to get use to the new reality. But as I think about it: I still have a problem with that aspect. because the mind of a mother can have a desire for a young fellow her daughter brings home but her mother self forces her to control her lust. And, we were shown a mother who was shown to be in control of herself for the sake of her daughter.
I agree. This was an interesting movie. A "sleeper" but in the end the idea is very intriguing and interesting.--MO
