You are about to see a movie with great atmosphere and good photography but it lacks on all other aspects. In my opinion the script was a great idea, but on the other hand it has severe flaws, i could give you an example but i don't want to spoil anything. The movie is really slow and i could understand it if it was for an artistic way in some scenes, but it seems that whatever happens the director follows the same tempo, maybe because of the complex scenario and that lead to less suspense for the viewer.
