This movie made me feel more claustrophobic than anything I've ever watched. I almost turned it off half way into it; but I couldn't make myself do it because I just had to figure it out.Initially, this unsettling sense is caused by the physical situations in which the characters place themselves. However, the feeling of claustrophobia evolves, as the movie progresses, into pure psychological claustrophobia as you, the viewer, become lost in the main character's recalled memories.It wasn't until very near the end of the movie (as planned by the film makers) that I realized what was happening: the entire movie takes place in the main character's mind as he sees his life flash before his eyes on the way to his death.You witness these final moments of his life (which likely include his last thoughts after impacting the ground too) reliving his decisions and regrets.The editing, lighting, camera angles and acting all fit together perfectly to build this story within a story, which takes place completely within the main character's head.I loved it and will watch it again as soon as I recover from the first experience...

For an obvious low budget movie (its definitely not your Hollywood money) it is an amazing achievement. When I look for a good horror film i look for atmosphere and this definitely created that. It created a knife edge, strange and odd European atmosphere which kept me intrigued to know more and the sense of the infection that grasped two of the characters was great as it made you wonder why it didn't get him therefore making you realise that the story is focused on him alone. Its a great watch as I have watched it 3 times. Definitely buy it, it is worth it. Also I like the creepy visions the guy has especially of the man with no face burying a body and the music corresponds well with the Russian underground and it creates an air of creepiness and makes you feel claustrophobic.

The director over used funky lighting effects and camera angles. My girlfriend and I both got headaches from it. I didn't really see the reason for their overuse.It was also hard to follow. People were appearing and disappearing, things were happening randomly - it just really didn't make much sense. I turned it off after a while. I don't care if I didn't get it or whatever, because I don't really think this movie is worth a terrible headache.To get a similar effect, sit in a dark room, turn on a strobe light and try to read a book in a foreign language.

As a True urban explorer i can say this movie is anything but true to urban exploring and completely unrealistic. If you have been urban exploring watch this movie and you'll know what I'm talking about. However if you've never been urban exploring DO NOT use this as a reference on how to do it as it is anything but accurate. To see what true raw undramatized urban exploring is just go search the web for urban exploring and you'll see what I mean...Urban Exploration is the exploring of areas that have been lost to society or abandoned and hidden to the world that no one knows about (except maybe the homeless) including tunnels yes so i will give the movie credit for that and the fact that you do have to have the proper equipment and research prior to going but not on the level of the equipment they carried...I mean who the hell carries a radiation detector on them...and they didn't have a respirator mask and they were also very careless with the use of their equipment especially flashlights waving them around in the open for police and others to spot them...and i have never heard of anyone using a body bag on an exploration as equipment...and in no way is urb-ex as described: "Urban Explorers are extreme sports' answer to computer hackers" it is not an extreme sport and does not involve base jumping ever, thats not a good way to escape the cops because you will be caught...base jumping is not urban exploring!!! Although it is true, urban exploring can be a dangerous hobby, it in NO WAY would ever present dangerous settings as the ones depicted in the film (i.e. - radiation) unless you reside or explore in a nuclear war-zone or in a area suspected of such conditions. thats what the research is for. Asbestos poisoning is a much bigger threat than radiation...It starts out with the explorers jumping out of a van and running out in the open to a small hole in the wall of a building with loads of gear on and super bright flashlights on their heads...because that wouldn't draw attention!!! and basically, without giving too much away...the plot does not tie together well mostly due to the fact there is a cut scene/shot every 3-5 seconds of the film including flash backs every other shot. as a matter of fact the plot is very vague and only implied. Unless you do some really powerful hallucinogenic drugs before exploring it will be nothing like the film. The main thing that made me upset about this movie was that it was a disappointment and let down as it claimed to be the essence of urban exploring but in many cases was not and was a total dramatization and blown ridiculously way out of proportion and in the long run turned out to be nothing about it in the final conclusion. This movie was just made (in my opinion) to try and scare people from going exploring and prevent illegal trespassing and encourage the safe tourism of historical landmarks open to public (partially because of the clips in the credits) but who knows, maybe it was meant to encourage urb-ex to find out whats really out there...or where you really are!!??? i think...On one last final note: I will say that it had a very interesting attempt to jazz up the hobby and make it seem more hardcore than it really is although in some areas it can, like the movie suggests, be highly dangerous and precautions should be highly taken into consideration...
