With a broken narrative, an abrupt and booming soundtrack, and a montage of interspersed dreams and realities, it's clear that the director is trying to tell the story of The Imitation Game and Oppenheimer in the same way that Inception did, with a disastrous ending.
The first half of the movie is a self-referential narrative of the hero's life, with random stuffing about the Sino-Japanese War, the Communist Civil War, and his sister's forbidden feelings for him (which part of the plot that I couldn't understand the most). The second half of the film is all about him having maniacal dreams inside the base and figuring out the math from them. Science is portrayed by the director as a joke, as rediculous as a Chinese dress-up Ferris wheels and merry-go-rounds imagined by a kid born in a rural area and sent to a closed base immediately after college.
The movie always depicts an enemy, be it the Japanese, the Nationalists, the Americans or his teacher, who is driven from a pure mathematician to a madman, and these pressures fall on the audience in equal proportions, while he himself suddenly figures everything out at the last second and then the movie comes to a screeching halt, leaving behind a bunch of pathetic viewers who have had a bellyful of vomitus and nowhere to vomit, and finally have to watch a bonus scene of the director's extreme narcissism.
