How is it possible for Ridley to make the sequels THIS bad?

Rating: 3/10 (18 May 2017)

Ridley Scott had the chance to, once again like in the 70s, make our jaws drop with an awesome movie that showed us that even a sci - fi movie could be a great thriller. Prometheus was forgiving, for building up a story for the next upcoming sequel, and here it is, the movie we have all been waiting for, but it's far from what we hoped for...
"Covenant" shows us nothing more than a mediocre plot, with the same story told all over again. Haven't we seen this already, two times before? The crew gets a distress call, just HAVE to investigate it, goes to the place where it came from, and then the caos starts (but this time with a bad CGI alien/aliens).
Ridley should retire and let his memoares go to the time when he actually made great movies. After "american gangster", there's actually not much for me to get from mr Scott. With the possibilities to make GREAT pictures with GREAT cast, like exodus, body of lies, robin hood and so on, he actually failed IMO, like in Covenant.
3/10.
