It actually took me until the 2nd act that I realized what they were doing with the narrative structure, and by the time the 3rd one came around, I was feeling very much like they should have gotten to the point. By that point, the movie is already at its last quarter and we're just hearing the same threads again and it was as if the movie was stalling for time. The closer it got to the end, it dawned on me that maybe it would never end up showing anything. And that's exactly what happened. So, in short, I don't feel the narrative structure worked for it, rather instead I feel it weighed it down and stretched the scenario to a point where it lost any tension. Worse yet, I don't feel like the movie took any particular position and ended up not saying anything as a result. It ends up feeling like it lacks the courage to say something.
It was frustrating because at times it was really good, but other times it felt like so much bureaucratic red tape behind the decisions that never amounted to anything on screen. As a scenario, it deserved much better. Maybe would have been better for the first half to be with the government orgs reacting to the threat, followed by a disaster-movie type of scenario of the target location in full panic mode.
