This movie was truly bad. Bad acting and no story whatsoever. Sometimes great kills and cute girls can save a horror movie, but this is not that time.
This is a difficult movie to review. On one hand there's the good: interesting first hour, Danny McBride is great and it is an Alien movie. But then we have the bad: it continues on the boring creators stuff from Prometheus, the plot is weak and predictable and it's not scary or gory enough. So it could/should have been so much better, but it's still good enough to check out. But please let James Cameron do the next one :)
