Ridley Scott's latest big space sci-fi adventure, "Prometheus" opens today. Originally intended to be a prequel to Scott's 1979 "Alien" film, Prometheus actually takes on a new story with new creatures, though fans of "Alien" will likely see some similarities.
The plot: It's the late 21st century. Scientists and adventurers travel to a distant planet that may hold the secret to the origins of humanity.
In general, film critics have liked the way "Prometheus" looks, but they've taken issue with some plot holes in the film.
