I was planning to work at the same time and I dropped everything to watch it! I think it's really good! Yes, I agree, it's not scary, but the tension is there all along and I'm not even talking about the music that gives me chills! Of course, there are a few hollow moments (in the sense that we explain everything to you, we do not necessarily let you find the rest yourself...), but I find the actors good, an excellent soundtrack and incredible editing! Well, a very good movie where you're having a great time!
