As Brad Anderson's second work, the film continues the gloom and mystery of "Part Nine". Christian Bale’s performance in the film also brings a strong personal style, not only skinny and sick, but also neurotic. This effect even exceeds the shock of the film’s narrative structure and plot itself.
The film has the characteristics of suspense and thriller at the same time, rhythm control and atmosphere creation are also very smooth, step by step showing Shen Ning's solemn pessimism and madness, director Blatter's overall control makes the film appear strange charm. The movie begins, develops, and ends in dark gray tones, and the situation is rendered in place, making the audience seem to be on the scene, in a hypnotized nightmare. In addition, the protagonist Christian Bale’s performance is very well done. He fully expresses the helplessness, exhaustion, fear and madness of the protagonist after suffering from insomnia. Throughout the screening of the entire movie, his performance has always attracted the audience.
