This was a brilliantly shot story, managing to be exciting and suspenseful throughout while also maintaining such a high level of artistic vision and messaging that it's a wonder I haven't seen this film before now. Not only is the total visual style top-notch in terms of cinematography and locale, but the story and characters are wonderfully written and explored surprisingly well throughout the film. I loved all of the characters for their own unique traits and qualities.  It helps that there are so few characters and places, allowing the movie to focus in and really talk about specific issues and events in depth. The entire mystery/thriller aspect of the film, that being the unreliable narrator(s), is a good one and done very well. It keeps the story engaging and is extremely entertaining. There's not much that is wrong with this film, its an interesting watch through and through, and definitely one of my favorite stories I've ever watched.
