Or do not wish for (to happen) for that matter. That goes for what happens in the movie. In the end though it does feel more like another horror movie, then a "history" lesson in french background. Of course this only loosely based on anything. And the fact that other movies have used similar approaches (Guard Post et al) does not help or improve on the viewing experience.
On the other hand, who knows how many movies you have seen. This might be the first of its kind and you might therefor like it more than I did. It's not a bad movie see, but it's just did not cut it for me either (no pun intended). Especially considering there is the British and a Korean movie, both handling the matter on hand better. Still if that is your cup of tea, you will like it.
