Watched it this week. Thought it was pretty poor, TBH.
Good idea for an Alien prequel, but in many ways a wasted opportunity. Sure, the SFX were OK, but how many times can they get away with the old "alien in the stomach" thing? Crappy script, ill-thought-out plot, poor acting, saved a little by the female lead (don't know her name). And the setup for the next one at the end sounds ominous.
Let it go, Ridley.
Interestingly enough it shares a writer with ST: ID and suffers with similar issues IMO - loads of it doesn't make great deals of sense.
Lindelhof is a cancer to movie making.
