Scott says: "This is a great commentary on the 40th anniversary of Kubrick's masterpiece."
The site includes this YouTube clip from an interview with Kubrick.
The famously sniffish Renata Adler got to weigh in during her short-lived reign at the New York Times: "There is one ultimate science-fiction voyage of a man (Keir Dullea) through outer and inner space, through the phases of his own life in time thrown out of phase by some higher intelligence, to his death and rebirth in what looked like an intergalactic embryo… Its real energy seem to derive from that bespectacled prodigy reading comic books around the block. The whole sensibility is intellectual fifties child: chess games, bodybuilding exercises, beds on the spacecraft that look like camp bunks, other beds that look like Egyptian mummies, Richard Strauss music, time games, Strauss waltzes, Howard Johnson's, birthday phone calls… [T]he uncompromising slowness of the movie makes it hard to sit through without talking–and people on all sides when I saw it were talking almost throughout the film. Very annoying. With all its attention to detail–a kind of reveling in its own I.Q.–the movie acknowledged no obligation to validate its conclusion for those, me for example, who are not science-fiction buffs. By the end, three unreconciled plot lines–the slabs, Dullea's aging, the period bedroom–are simply left there like a Rorschach, with murky implications of theology. This is a long step outside the convention, some extra scripts seem required, and the all-purpose answer, 'relativity,' does not really serve unless it can be verbalized."
