I'll agree with this reviewer, who voices some disappointment that the theme of grace seems mostly passive and might have been portrayed with more complexity (i.e., grace in the form of a courageous self-giving). However, it is not like the portrayal is shallow. We see the tension in the characters themselves, and even see the two most willful characters come to a point of confession between them. We see both the beauty and horror of nature -- with the former writ large and the latter haunting the whole -- like a National Geographic film except with a full dose of self-consciousness about the questions of meaning. When it comes to the human narrative I suppose I was wishing for was a truer picture of the (seemingly foolish) courage of grace. But I suppose one can't fault a film for not having a full-blown Christ figure. In fact, if it had one, we might be criticizing it for spoon-feeding us instead of leaving us with the longing. Perhaps what the reviewer is on to -- the concerting thing about the film -- is that it is so realistic; nature does always seem to have the upper hand. But even with its harder edges, it looks gorgeous.
For me this film was an 8/10 (which for me means it was very good), and I wouldn't fault anyone for giving it full marks.
