Maybe it's just not having seen a really good thriller mystery in a while, but this is excellent! I don't know why it's listed as horror though. Two small nudity scenes but they are part of the overall scene and not just for T&A. It starts to have a surrealist ending but then just straightens itself out in a way that normally disappoints me. It works here. Really no spoiler except for the mystery fan. Keep an ear open for names.
Edit: there's no undertone political messages in the movie!
