Mine 9

I thought I knew what coal mining was about. But the truth is I had no clue at all. This movie is especially interesting for its realism and the attention to details. I discovered some harsh working conditions, not happening in the 18th century but in modern times and that makes it even more frightening. The machinery is more interesting than in sci-fi movies, and the tension is higher than in alleged horror movies. There are imperfect things, but as a whole, Mine 9 is very impressive.
