Does this summary says enough? If you don't know what I mean let me explain. If you will have 100 geeks well I guess maybe 5 will like this kind of flick. It do has the feeling of 2001 A Space Odyssey. It is extremely slow and a pure throwback to Sci-Fy from the seventies without aliens.
The score used is also back to the eighties or late seventies, the colour grading on the other hand did remind me of Begotten (1990). Extra saturated moments and editing that also makes you go insane.
The story itself is simple as it could be, captured and trying to escape, as simple as that.
If you like your movies very weird this is your thing. If you like stories full of questions, pick it up. It do has a horror feeling here and there what makes it more weird. But I can agree with most reviewers, bad ending.
