There's an indie film I quite enjoyed called The Hunter, starring Willem Dafoe, that fictionalizes the demise of the last remaining tiger. I recommend it highly for the outdoor landscapes and non-traditional plot alone.
I thought the film captured the tone of the book extremely well, perhaps more than any adaptation I've seen. I loved the fact that the film explains very little (and neither does the novel), just lets the story tell itself through images and sound. Both are underappreciated gems.
Recently I've been enjoying films that cover little niches of the world, geographic or otherwise, that I know nothing about. Another good example is Premium Rush (2012). I don't know if there's a name for this genre, as on the surface the films look nothing alike, and can vary wildly in quality, but there's just something engrossing about them.
