Presented in what appears to be a single long take, this action movie is expertly and impressively choreographed; too bad the same attention wasn't given to the dull story or flat characters. Following in the one-shot tradition of Silent House, Birdman, Bushwick, and 1917, One Shot begins in an aloft helicopter and follows its characters into office buildings and through a battlefield with characters hiding behind storage sheds, convenient arrangements of metal barrels, and stacks of wooden crates. It feels very much like a video game; it's impossible not to be aware that all of these pieces have been built this way, that every obstacle and shield has been placed on purpose.
Like a video game, the movie can even get your adrenaline going with its unpredictable violence. But even a video game has a story; it has levels, side-quests, and other things designed to create an experience. One Shot is pretty much more than an hour of shooting, explosions, blood spurts, characters hitting the ground, and little else (except for lots of banal shouted dialogue). One crucial story element is withheld, for no reason, until nearly the end, when it could have prevented all the trouble if it had been mentioned earlier. The movie seems to care little about things like this -- or about its human characters, who die dispassionately, without any feeling. It's too bad the colossal amount of work put into setting all of this up led to such a monotonous movie.
