The performances are excellent throughout. And, the film builds the tension carefully and wisely as the stakes get higher as the film moves towards its conclusion.
The visual effects won an Oscar in 1969. They are no where near the level of 1968's "2001: A Space Odyssey," but that isn't a surprise, as effects never got back to that level until 1977 with "Star Wars" and "Close Encounters of the Third Kind."
That's basically all it is, is astronauts being marooned up at space which is so uneffective and dull in comparison to "Apollo 13" and "The Right Stuff"- this film can put anyone to sleep with all the pointless blah, blah, blahing. Won an Oscar for special effects competing with!!!!!!!!
