I get why the critics gave it the positive reviews they did; the cinematography was outstanding and the direction and performances were all very good. I enjoyed it a great deal for those reasons. However, I also get why much of the viewing audience was less positive about it (like the two friends I went with.) It is most definitely a slow burn, psychological horror film that lacks the in-your-face shock and/or gore moments common in the majority of contemporary horror films. It's also bound to leave you with more questions than answers (as one friend complained, "There's not enough info!") If you want to see an extremely well made film and aren't put off by films with a slower pace that demand a bit of imagination, I highly recommend it. Seriously, some of the camera work is breathtaking.
