Horribly disappointing.
They had some real potential with some of the themes and story devices, and the action hit hard at some moments. However, the main character is made out to be some sort of hero while at the same time trades out all of his values and betrays his friends for the empty and vacuous reason of keeping his job. Honestly one of the most hauntingly shocking films.
I wasn't going to bother writing a review but it kept me up at night.
He is a major loser.
