>>>Spoiler Review<<<<<
Not as good as Prometheus.
Covenant seems to be like a small chapter specially about David and a bridge to the next, possibly big event. The movie was quite unidimensional with a simple plot. But Scott did manage to further expand the Alien universe and continue what he started with Prometheus.
The Neomorphs stole the show! They were vicious and terrific. From the trailers, they looked quite meek but man, they gave the chills & thrills. It was exquisitely designed creature, wish more time was given for them. The scene where David & the Neomorph try to communicate with each other is wonderful.
There aren't grand moments and concepts like those in Prometheus; but the movie does give bits of philosophical ideas & mind-set of a carried away Robot. Fassbender's dual role is worth watching but nothing extra ordinary because there wasn't such content which he could pull it off. Some unique moments of David & Walter exchanging ideas & playing flute is just what held the movie during its second and slow act.
All other characters including Daniels are quite cardboard cut outs because again there was nothing more written about them other then to scream, die, pass guns, hold guns, aim and shoot.
The sets & visuals are good but not as grand as Prometheus. The only grand scene was the Black goo bombing sequence. Whereas, the interior sets of the Engineer Citadel was quite disappointing as it were quite bland and not much of their world were shown other than a hall and few small rooms which David converted into his lab. If you expect the signature Off-wordly designs, you aren't going to get it.
With this movie, Scott ended the most anticipated & intriguing adventure of Dr. Elizabeth Shaw by having her killed. So, with no Shaw, the movie feels half empty.
The Xenomorph is superb and better than those in any other Alien sequels. But the ending was rushed and there was nothing unique in having the Xenomorph expelled into the space from the airlock. Alien & Aliens did it a lot better and nothing can beat its final act.
May be repeat viewings could help me catch more and change by mind but until now, purely for the Neomorphs, Fassbender & the Horror, I give it a 6.5/10.
