I think that this film took the best elements from "Prometheus", and added them into a film more akin to the original "Alien". In that, I mean that it further developed the ethical commentary started by the first film, but took more of a horror angle. It definitely worked for me, as it kept me thoroughly interested. It also added to the mythology of the series in a unique and interesting way. That being said, the ending of the film was really predictable. I saw the big twist coming far before it actually happened.
Apart from one scene (shown in the trailer), where the Xenomorph looks a little cartoon-like, I thought that the CGI was pretty good as a whole. The production design and cinematography also establish the tone of the film extremely well. The acting of the film was also really good. Michael Fassbender is very intriguing in dual roles, however, his American accent is a little jarring at first. Katherine Waterston is really good in her leading role, delivering a stronger performance than I expected. Danny McBride also surprised me, doing much better than expected in a serious role. And James Franco was... great?
Overall, I really liked "Alien: Covenant". It did a very good job of setting the series on the track that it needs to go before leading up to the original film, while keeping the commentary that I loved so much about the original film. I think that fans will be satisfied.
