I personally found it to be a great movie. The action was awesome. The emotions felt real. I've noticed that people complain about character development but I don't believe that's what this film was about.
Here is what I felt.
A desensitized woman brings basically a kid to the world of combat journalism. Through this we get to see what war does to people young just getting a taste and old seen some things.
War is chaos and this movie shows that.
