Some reviewers have tended to confuse the courageousness of the film (look, it's a nice film, but it isn't especially daring - it's a conventional "battle against-the-odds" survival rap) with the courageousness of the underlying story. Personally, I didn't find the political/historical context that interesting, but there was more than enough cinematic artistry in Rabbit-Proof Fence to make it a very worthwhile experience.
It's a very simple, linear tale. It's gorgeously photographed and the soundtrack (both Peter Gabriel's music and the 5.1 surround mix) is very involving. The narrative isn't really important - the story does little more than document, episodically, a long journey home across a desert. But this provides a terrific figurative platform; the fence represents not a barrier but a lifeline, a map, a way home and in one exquisite moment, a heartstring: a shot of the girls first grabbing the wire is artfully spliced next to a view of their mother, 800 miles away, holding the same wire, pining for her daughters.
Nice editing, that man.
