Has anyone else see “The Wall” (Die Wand, 2012)?

Important: can you explain it to me?

I ought to feel bewitched by this beautiful and haunting film — the debut by Julian Roman Pölsler — but I also feel annoyed, as if it circles around a metaphor or a broader statement about something that I can’t figure out. Please help.

The Wall is basically a one-woman show (streaming on Netflix right now) about a woman (Martina Gedeck) whose friends invite her to stay in their hunting cabin one summer next to a breathtaking Austrian lake, surrounded by spectacular peaks. But when she wakes up the next day, she finds that an invisible wall surrounds her, separating her from every other human being, including them.

Her story of survival goes beyond being remarkable — what would you do if you found yourself without any access to human contact? The film reminds you of the skills you probably don’t have: the ability to milk a cow, gut a deer, mow a field of hay using only a scythe, help the cow give birth. I’m not sure it’s possible to watch this film without getting a little survivalist yourself: must watch YouTube for advice on how to help cows in labor, just in case.

All of this combines a great atmosphere of dread/horror with science fiction (where did the wall come from?) and her heavily narrated tale of psychological transformation. But what does it mean, in the end?

I’m also sorry to say that huge narrative gaps. I understand the impulse to survive, but why isn’t she more interested in the metaphysical questions? Is this woman’s tale of survival intended to have a feminist edge — and if so, why can’t I find it, what with my nerve endings constantly attuned to such things? Why doesn’t she just keep the sweet little white kitty inside the house? Why do I just not buy the sudden arrival of a [identifying information withheld] later in the film?

Please tell me you’ve seen it and have ideas about What It All Means. Surely there’s something I’ve missed. I want to like this film but find myself oddly annoyed at the cloaked significance and narrative leaps.
