...[Kubrick] is necessarily spurred to invent actions - objective correlatives - that reflect the novel's psychological drift; the characters' thoughts and emotions are thereby demonstrated, not baldly declared...if a film's revelations about life are to be meaningful, they must be advanced obliquely, so that the audience is permitted the "thrill of discovery" of the truth.
Jenkins
Themes
It is characteristic of Kubrick that while one part of him pays intellectual tribute to the rationally constructed master plan, another part reserves the skeptic's right to anticipate human imperfections or the laws of chance that militate against its success.
Walker
Narrative and Style
...Kubrick employs the straight cut, often a shock cut, as his preferred method of shot transition...it can be a...spectacular kind of shock cut, such as the elliptical cut from bone to space-ship [in 2001], which connects the shots graphically as well as metaphorically and thematically. This is one of the most momentus cuts is the history of cinema, not simply because it moves the narrative forward four million years in story time, but because it comes after a lenghty sequence containing no dialogue or conventional exposition. It is a startling, aesthetically audacious narrative moment and a good example of how Kubrick takes a banal device and gives it major significance.
