Welcome Heatherzilla. Please don't flame me

(bad pun, sorry, couldn't resist!).
I like sci-fi too. In
2001: A Space Odyssey, the world's first murder is committed (when one man-ape kills another with a bone weapon), and then in the "future" (now past), the spaceship's computer HAL commits mass murder when he assaults one of the astronauts in space, and asphyxiates the three who are in hibernation. Always thought that those were original concepts that went unappreciated.
Hope you enjoy it here.
