My top 3 Sci-Fi movies.

Jeff-B: At the movies.

Moon explorers encounter a monolith that points them to a destination near Jupiter. In flashback, we see another size of the monolith playing a key role in human evolution, i.e., we learn how to kill. An expedition is launched to investigate the Jupiter possibility. Two young astronauts and a bunch in suspended animation spend months in space, passing their time partly in communicating with the human-like brain of their ship's computer, HAL. HAL malfunctions and causes the death of all the suspended animation passengers as well as one of the "awake" astronauts; the other one barely survives and figures out how to disable HAL. He arrives alone at the Jupiter destination and undergoes a series of cinematographically confusing experiences that amount to his final appearance on the screen as a giant fetus.

Best Sci-Fi film ever.

Deckard is a Blade Runner, a police man of the future who hunts down and terminates replicants, artificially created humans. He wants to get out of the force, but is drawn back in when 5 "skin jobs", a slang term for replicants, hijack a ship back to Earth. The city that Deckard must search for his prey is a huge, sprawling, bleak vision of the future. This film questions what it is to be human, and why life is so precious.

Ridley Scott's best movie to date.

When an American nuclear submarine crashes, the United States Government believe the Russians to be responsible. They enlist the help of a team of underwater drilling platform workers who are to help the deployed Navy SEALS locate the crash site. As they get closer to their destination, the friction between the two teams increases. When some workers report seeing UFO's underwater, the SEALS grow increasingly suspicious and suspect a Russian mini-sub. After a series of near-fatal disasters, the workers find that they are the only people who are capable of stopping World War III. But they are not the only inhabitants of the deep, and strange things are happening back at the surface...

Back when James Cameron made GOOD movies
