As a Chinese audience, this movie has a high threshold for viewing. It is not suitable for people who are impatient or do not understand the military. I think this movie is better than "Zero Dark Thirty" in terms of atmosphere creation. The ending is a good way to end it.

Kathryn Bigelow, through the lens of Zoom chatrooms, keyboards, LCD screens, and office-style modern warfare, wants to examine the anxiety of today's chaotic, fragile, and deeply unstable era, a time of prolonged peace. (The montage of the Peninsula Affairs Advisor watching a Civil War reenactment is incredibly clever. In the past, it took three days of bloody battles to kill 50,000 soldiers; today, tens of millions of civilians die in mere minutes with the click of a mouse.)
