It's no definitive masterpiece but it's damn close.

The film creates a perfect balance between action and depth of basic needs, in the midst of an infertile atmosphere.

The movie's neither hopeful in contrived ways, nor hopeless in different contrived ways. Somehow it manages to be wonderful

While it is a pity that the story wasn't told with more visual finesse, this is trivial compared to our real-world problems. It takes a good movie to put that into perspective.
