Prometheus (15A) isn’t so much a prequel to Ridley Scott’s Alien trilogy as it is a greatest hits package, as feisty heroine Dr Shaw (Noomi Rapace) tracks down what appears to be the human race’s genetic ancestors to a planet half a trillion miles away, only to discover that the god-like beings she was expecting to find are more akin to the Old Testament God that liked to dish out punishing plagues.
