I agree with most of the negative comments about this movie.It is a gigantic missed opportunity.My biggest issue apart from the utter predictability and nonsensical,inept script,was the disappointment of seeing 'Prometheus' mixed up with 'Alien'
Alien covenant gets locked up in its own self importance while forgetting why we loved 'Alien' in the first place.I really wanted to like it but came a way  with a huge sense of disappointment
