There is something about the beginning of this movie that makes it suspenseful even before any action happens. If you grew up in a regular town nd home, chances are you have heard of this movie. It has actually had the title "Scariest movie of all time" which is correct to a certain degree, because for its time, it was indeed extremely scary. No sex or nudity, violence is strong as the first event that happens with the alien is the alien comes out of an egg on of the astronauts finds an latches onto his face for awhile. The second thing that happens is tha later on in the movie, the alien unlatches from the astronauts face and all seems well...until later, while eating dinner, the astronaut starts coughing and collapses on the table. Then the alien bursts out of his chest looking like a little baby alien. Then it runs off into the ship to grow to a full sized lethal alien. The rest of the movie is filled with suspense and action, with everyone dying except one astronaut. Keeps the action until (literally) the very end of the movie. The alien is disturbing to look at, though.
