On the performance side, it is only really Michael Fassbender that is served anything meaty enough to get his teeth into. Playing two synthetics, David and his upgrade Walter, Fassbender is reliably great, delivering a sharply nuanced performance that highlights both synthetics' similarities and differences, helping to feed into some marvellous plot developments later down the line. The flute scene is easily the standout moment of the entire film, mainly down to Fassbender's disconcerting and mesmerising performance, providing a moment that deserves to enter the franchises' highest realm. Nobody else really gets a chance, with the script failing to flesh out individuals well enough to deliver any satisfying character work; an opening moment that should be filled with devastation attempts to instil an emotional weight for the film to run on, but it only lasts so long and is largely forgotten until a last minute line-drop towards the end of the film. The talented Katherine Waterston thanklessly drags herself through Covenant with a solid performance, all things considered, and will hopefully use it as a platform to move on to bigger and better things, particularly after her terrific performance in last year's Fantastic Beasts & Where To Find Them. No one else really stands out, which is a shame considering the talent involved.
The one thing that convinced me to give Covenant a watch, despite my lacking interest in the series in general, was the beautiful marketing - the trailers were effective, the posters and artwork were outstanding and, helmed by Scott, it would likely impressive at the very least visually. It does, but it doesn't utilise its resources all that efficiently; the scenes are occasionally poorly lit and as beautiful as the production design is, they are not given the opportunity to impress as frequently as you would like. Act one captures most of the beauty, with the sequences of the planet's exploration finding both some excellent cinematography and genuine excitement, wrapped together with Scott's atmospheric direction and careful build-up; from then onwards, it doesn't collapse as such, just fades from notability, overpowered by the frustrating supporting characters and duller palettes and saturations. Scott is always attempting to heighten the intensity and draw audiences in but those on the outskirts will struggle with it, particularly when the CGI leaves a lot to be desired. While they are terrifically and undeniably well designed and conceptualised, the movements of the aliens do not always feel properly rendered or natural, causing stilted movements and a general underwhelming aftertaste.
Summary: Alien: Covenant is somewhat alienating for casual cinemagoers, producing a for-the-fans affair that attempts to get by on the back of what preceded it, which not only undoes some of the brilliance of Alien and Aliens, but creates an empty spectacle in the here and now too.
