Not sure how many horror fans here, but if any interested on your thoughts of what I have now consider to be the best film in the genre made in the last couple of decades. Definitely the most thought provoking and creative, and one of those non-conclusive endings that challenges and sticks in your brain for (too long). And to avoid tragedy if you haven't seen it, you absolutely have to make sure you are watching the 2008 french/Canadian version. There is a 2015 version that is absolute garbage.
