I've found this movie to be very graphic. Personally, I'm one of those people who wanted to follow med school but decided that performing autopsies is not really something I want to do on a daily basis.
Well, half of this movie is an autopsy with virtually nothing censored. You get to see everything and while I can't say if it is accurate or not, it is rather graphic.
That being said, I must give it to them, it is a good horror movie. It is a smart horror movie I may add. The plot doesn't make a lot of sense and there are many, many questions unanswered (personally, I find the end totally anti-climatic) but it builds tension slowly and nicely. Yes, at the end you ask "who was that, why, where, when, how the heck
" and you'll get no answer whatsoever. Actually, for all intents and purposes, the movie puts a lot of questions and ends with answering only one of them.
So from this point of view, there is no finality, there is no sense of satisfaction. When the movie ended, I expected something else to happen, to explain, to show. There is an overall answer and theme that is explained but it ended when it got interesting. However, from a horror perspective, pacing, tension building, it works just fine. It feels like playing Silent Hill, the horror game.
So it is a strange hybrid. The concept itself is relatively neat and unused. I haven't seen any movies do this and I've seen my share of horror movies. Actually, I can say that the entire exposition is fresh. Even if it is low budget, it never feels this way and apart from transitions of 30 FPS to 60 FPS (for cinematic effects), it looks really nice. The characters are believable and the story in a way actually makes sense.
But the problem is that while the concept is good, while the story is good, it builds up to something and that something never happens. And that's why I can't give it more than a 7 / 10.
