Initially, I thought this was just a pretty shameless attempt to attach the "Alien" brand to the really mediocre "Prometheus" (2012) but to be fair, it is just a little more than that. The crew of a colonial exploration ship are heading to a new word when their crew are tempted by a bit of John Denver, and divert to a seemingly far more suitable planet. Of course, once they land they begin to realise that nothing is as idyllic as they had hoped, and getting off as soon as possible is now the order of the day. It's almost 40 years since the first film of this strand, and that renders most of the shock value pretty impotent. We have all already been through the gamut of terror that these stories deliver and even though Sir Ridley Scott is an old hand at creating a sense of menace, it's all just a bit so what with this predictable plot that ends, then it ends, then it... ends! Michael Fassbender is quite effective as "David" but the rest of the cast, including the usually reliable Billy Crudup have little by way of original substance to get their teeth into. It is certainly a good looking film, but that's what is expected, it is the derivative storyline that lets it down. Indeed, it did remind me of an old "Star Trek" episode with some mythological "Sirens" thrown in for good measure. Still, it is quite watchable, just not a film I expect you will ever remember.
