Time Out says
Hyams' sequel to Kubrick's big daddy of sci-fi movies may not have the novelty of 2001: A Space Odyssey, but it is still a better film than anyone could have dared to expect. Scheider plays the American space agency boss trying to find out what happened to the ill-fated 'Discovery' spacecraft and its surviving crew-member. He joins a Russian space mission to Jupiter captained by the formidable Mirren, but things get pretty sticky when news comes through that back on Earth the super-powers are on the point of war. Hyams has not come up with a climax to match Kubrick's rush through the star-gate; but this is still space fiction of a superior kind, making the Star Trek movies look puny by comparison.
