Not an action movie!
I tend to like movies with onion layers to their central conflict, and this one did have them. It was not well written or acted though. Echoing the opening scene of WarGames, the movie explores the well- trodden dramatic area of 'orders versus morality' found so often in movies such as A Few Good Men.
Better Dialogue, character development, and acting would add to this and crank up the tension. The perfect soldier (trainee) was difficult to believe as having moral qualms. The fundamental difference between warfare with piloted versus drone aircraft (in harm's way) was all but ignored with more of a focus on collateral damage. Well, F22's kill innocents too, so I have trouble understanding why the trainee has reservations. Assuming her strong education, not only in the military, but in theories of war and government, she should have come to grips with "following orders" long before she was put into this situation. The senior pilot (trainer) was a reasonable 1-dimensional character as the pizza- eating, video-gaming pilot that had no care in the world. The character growth and changes in point of view during the movie is sudden and slightly inexplicable. Additionally, the contact with the chain of command and the lack of support from the military for this pair of drone pilots was unbelievable.
As all of the action takes place in a desert trailer, this movie would be better-suited to a stage presentation.
