Fantastic film! I watched it not too long ago, and for me, it's a great Lovecraftian period piece PACKED with atmosphere and a nice dark soundtrack.
The movie (and main actress) is cute though; built good.
I will want to watch it again and again.
Seriously though, without spoiling, I just want to say that I have a hard time deciding what I liked more about this: The mystique of the Kola borehole?
The set designs--particularly the resort level?
The old guy with the elevator key "acting stupid" to get what he wants?
The ever present, ever mounting dread?
I can't decide--yes, go watch this!
