I have to watch it. It's my job, but I think I might want to hold off on this one if I were you. There are some tantalizing (read: gruesome) imagery in this thing and definitely reveals more alien life forms from the movie.
Here's the storyline for the movie:
Ridley Scott, director of “Alien” and “Blade Runner,” returns to the genre he helped define. With PROMETHEUS, he creates a groundbreaking mythology, in which a team of explorers discover a clue to the origins of mankind on Earth, leading them on a thrilling journey to the darkest corners of the universe. There, they must fight a terrifying battle to save the future of the human race.
So watch it if you dare! SPOILERS **YOU HAVE BEEN WARNED**
PROMETHEUS opens on June 3.
