This movie is not for everyone, you either are okay with the movie or dislike it. The story is about work pressure, and since I am from the EU (where the work pressure is quite low) I found this movie interesting. The story is slow paced, but shows from every person a back story and you can possibly relate to them. Sadly the execution was a bit messy, there were a few flaws and real movie mistakes. That said, I could feel the suspension throughout the movie. The actors all did a very well job, I wish some had more time to develop their character. I didn't found the music pleasing at all times, and I don't think I would rewatch this movie. Watch this if you like suspense / mysterie movies. Skip this if you want a clear answer at the end of a movie.
