It is just annoying when the movie keeps building up mysteries and ends without a shred of answer or explanations to those mysteries.
For me, it was a total waste of time. If the director would just keep coming up with strange events that he does not intend to explain, we might as well see flying unicorns in the middle of the movie, because he would not have to explain anyway.
In the middle of the movie, strange events do happen, but at a slow rate, they are not exiting or big science fiction sort of events. The imagination that was put into those mysteries is so limited. It seems like more of a cheap fiction movie, with limited production limited ideas. But even with those limited scope ideas, as a viewer you demand an explanation that might make it good or bad after all, but guess what, no explanation is offered what so ever.
