Alien

There may be debates over whether movies portray aliens positively or negatively, but “Alien” shows that all bets are off. This is possibly THE perfect sci-fi/horror flick; in fact, it doesn’t even suffice to call it such.

In deep space, the crew of the commercial starship Nostromo is awakened from their cryo-sleep capsules halfway through their journey home to investigate a distress call from an alien vessel. The terror begins when the crew encounters a nest of eggs inside the alien ship. An organism from inside an egg leaps out and attaches itself to one crew, causing him to fall into a coma.

From the moment when the egg attacks Kane to Ellen Ripley’s battles against the title character, this movie has you tensed up every second of the way. You may be very suspicious of every movement around you after watching this movie.
