Stanley Kubrick's 2001: A Space Odyssey took five years and $10 million to make, and it's easy to see where the time and the money have gone. It's less easy to understand how, for five years, Kubrick managed to concentrate on his ingenuity and ignore his talent. In the first 30 seconds, this film gets off on the wrong foot and, although there are plenty of clever effects and some amusing spots, it never recovers. Because this is a major effort by an important director, it is a major disappointment….
2001 tells us, perhaps, what space travel will be like, but it does so with almost none of the wit of Dr. Strangelove or Lolita and with little of the visual acuity of Paths of Glory or Spartacus. What is most shocking is that Kubrick's sense of narrative is so feeble. Take the very opening (embarrassingly labelled The Dawn of Man). Great Cinerama landscapes of desert are plunked down in front of us, each shot held too long, with no sense of rhythm or relation…. [We] are painfully aware that this is not the Kubrick we knew. The sharp edge, the selective intelligence, the personal mark of his best work seem swamped in a Superproduction aimed at hard-ticket theatres. This prologue is just a tedious basketful of mixed materials dumped in our laps for future reference. What's worse, we don't need it. Nothing in the rest of the film depends on it. (p. 24)
