A very slow moving movie that does rely on the mood it delivers and on suspense that is created by not giving the viewer too many answers. On the other hand I would understand if some wouldn't even have any questions to begin with. You have to let yourself go with this one. You have to be a real believer if you allow the pun.
Having said that, the movie is not really bad at all. The setting is good enough and the cinematography works for the movie too. The acting is ok, although there is not much to see and as with the pace some may feel it is a bit of a drag overall. So if you can limit your prohibitions and can overlook some of the flaws, you may very well be able to enjoy this
