Nothing short of classic horror film-making here. It could have neatly fit into John Carpenter's apocalyptic films, specifically Prince of Darkness to which it seems a spiritual sequel of sorts. It kicks off a disturbing scenario from the first minute and plummets straight into nightmarish soon enough. I haven't seen this kind of enjoyable and well made practical effects since the 80's The Thing, or perhaps as late as Species. No glaring and cheesy CGI is to be seen. What there is of CGI budget is all splurged on gorgeous otherwordly scenes. The main set has the lovely dichotomy you would find in a classy Silent Hill hospital, with juicy decorations from Clive Barker's Hellraiser. The people who made this clearly knew what they were doing.Tired of teen splatter films? Seen one ghost movie too many? Do jumpscares make you groan and roll your eyes? Try this. You won't be disappointed.

Awesome practical effects and very good production design. There are some great visuals and gross out scenes, along with a fitting soundtrack and solid lighting. Where the movie loses it a little for me is in the script and acting. Clunky exposition, thin characters, acting that's not quite there... it all makes the whole fall flatter than it should with such amazing technical work.

Very beautiful and very interesting film. A kind of hororro I have not seen for many years. I recommend it. I liked a lot its atmosphere and a very accurate photofraphy. Excellent also the soundtrack that creates a unique atmosphere. Very good also the director in this kind of story

Not sure why this movie isnt rated higher. I saw Cold Ground before this - and it had a rating of 7 something, yet it was another cliched found-footage tripefest, very dull with screaming women and glimpses fo monsters in torchlight. Yawn. This movie overall feels a little bit amateurish, but in a a good way, the way that means they are more likely to take risks, rather than follow what a studio would like, to get a "horror lite" product. The story isnt bad and visuals of the bad guys in cloaks are excellent. The setting is a virtually abandoned hospital. I have to say that with the evil doctor and all, it felt at times like Hellraiser 2 (my fave in that series for dark feels). The monsters were great, creepy and fairly uncompromising, as well as the results of the medical experiments tucked away in the spooky basement. The sotry was very well paced without too many cliches. The evil doctor had a good motivation for being that way, with the inclusion of occult worshipping into the movie. I was very impressed with this and the last scene is fairly spectacular. Well done to the makers of this film for making something quite groovy in horror.
