Bizarre movie...

Yeah, original is right. I personally didn't care for it very much. I didn't think the slow burn had a particularly good payoff. It was a rather simple story, with little meat on the bone. I feel like it was inching towards some greater overarching themes, but it kinda fell short.

It's just sort of a modern folk tale basically.

I enjoyed it overall, but was left wondering what I was supposed to get out of it by the end.

I'll offer two stabs at it.

Perhaps it touched on the psychological impact that children face when raised by one set of parents and are then forced to transfer to different parents. Ada was instructed on how to find her way home right before her surrogate father was shot. As she was led away by the biological father she looked back over her shoulder to the only father she had ever known. Perhaps this implies she would later try to find her way back to the home of her upbringing?

The other thing that struck me was the "mother" and how she didn't pursue Ada (after having done so once or twice earlier in the film). Was this the final breaking point for her -- that letting go was a part of life and had to -- finally -- be accepted? She had lost her daughter, now her husband, now her adopted daughter. Maybe that was a moment of breakthrough for her.

Having said those things I've explained nothing. I have no idea. But as I said I did enjoy it.
