Well damn, am i late to the party! Considering the film is 4 years old, I won't be using spoiler tags.
Having both watched the Theatrical and Chaos Edition versions of the film, I definitely have to say that it's a film that would've benefitted from the inclusion of certain scenes that created a better relation to characters from the opening moments of the film; effectively including the Prologue with David/Shaw to a certain extent, as well as the Last Supper, Crew messages, and the WY interviews.
Aside from characters, the gore of it all was really f**king brutal, and the story was interesting, albeit a light retread of Prometheus in ways. The atmosphere was great, the neo/proto designs were interesting, although felt underutilised until the halfway point/ending of the film, and the xeno itself was goddamn gorgeous.
Now i could go into a tirade about how the inclusion of Ridley's obsession regarding Androids and AI and the creation of life is starting to go a touch stale, especially with the mentality that he created the "first" non-traditional xenomorph, but i'd much rather sit on the sidelines and go by self-canon that Xeno Prime does exist, as well as the queen mother, palatines, praetorians, etc, and the Xenos are actually a creation from the Engineers, and that Predators hunt them for sport.
All in all, the film itself is quite a decent bloody and gory ride.
