We only managed to sit through the first 11 minutes before calling it a day. I think we did pretty well considering.
The cinematography and soundtrack were repetitive and disjointed. It looked like they only had one camera to shoot with and so every scene (within the first 11 minutes) was chopped together with the same imagery and sound effects. It was funny the first 2 or three times, we even joked "I bet they show the sky again" but they kept on doing it! The result wasn't eerie or sinister but it did give my wife and I a headache.
I don't feel its fair to comment on the acting as I only watched 11 minutes of the movie and didn't see any.
As for the reviewers that gave this such an astounding review. Well done! You got me! (for 11 minutes anyway).
For everyone else - AVOID AVOID AVOID!
