This movie is an amazing blend of science fiction, horror, and thrills.
A CIA agent recruits a couple grunt soldiers to track down a religious leader in Afghanistan to interview him.
But the soldiers soon find out that this is just a deception to lure them deep into a remote region of Afghanistan. What follows is a thrilling, scary, and exciting film that almost never lets up until the ending.
The writing is great, there are no over the top lines and long philosophical battles between characters, this is a movie about soldiers and they speak and act accordingly. The acting is fantastic, characters seems genuinely scared and nervous whenever appropriate. And the plot is a fantastic twist on the usual 'small company' war story movie as it adds elements of supernatural horror and psychological terror as the main antagonists instead of rival soldiers.
The cons are the slightly low budget special effects at some points, instead of showing poorly done CGI, I would have opted for the 'less is more' approach and focused on characters reactions to the supernatural phenomenon instead. The ending was a bit disappointing as well as there is very little concrete resolution but with some creative assuming and inference it is relatively obvious as to what happens to each individual character.
If you like horror or thriller movies or just want to see a fresh idea then absolutely give this movie a chance. It's a bit nerve wracking if you're watching it in the dark and definitely not for children. Adults however, especially those into film, this deserves at least rental.
