Sort of entertaining movie, but not worth watching twice

Rating: 7/10 (18 October 2016)

Trailer made the movie look very interesting and I like sci-fi and Nicolas Cage. So I was very hopeful.
The story line seems very interesting, because I like the thought that someone can predict the future and then the people who read the prediction don't first believe it to be true. And at some point they realize that there is a big catastrophe ahead and they need to save the day and people on Earth. (I do like apocalypse movies also.)
In the first half of the movie everything was great: I felt the excitement rise and it looked like there was even going to be a dash of thriller in this movie. The stones and the creepy shadows created something interesting along with the mysterious numbers.
But. Then comes the but. Somewhere closer to the ending or after the mid of the movie seemed like the movie makers just lost interest. The excitement was lost and the ending was too obvious and predictable. Okay, it fits to a sci-fi movie, but it fits too well. It was more like: "oh, you just didn't feel like using your imagination to create something different." I was so disappointed, the ending just ruined the first half of the movie. Plus I didn't realize them explaining what the black stones were about. They were there almost from the beginning to the end and still didn't get proper explanation. Shame.
I think Cage does good job, so he is the reason I gave this more than 4 stars. Knowing was sort of entertaining and okay way of killing time, but I don't think it is worth watching again. Not sure if I would recommend this, at least maybe not to someone who has seen more than two sci-fi movies.
