What a great concept gone to the trash. I usually don't write about movies but I feel really bad about this one.
When I saw the trailer I was intrigued by the concept, and until the end I kept on thinking "Something will happen now"
But nothing happened.
Just nothing.
They came, they tried to get out of a place no one has any idea of, they died trying, end of story.
P.S. - Actors did an amazing work. I am sure everyone did except the writer.
