Problem with Alien Covenant, is when David cut his own hair to look like Walters. It would have been obvious to Walter (who presumably has a high IQ) that David was showing motives to replace him by looking like him.
Also continuity error. Blood on woman's face. Then next scene no blood on face. Then blood on face again. Still totally forgiven!
Other problem is the conversation at the beginning by Peter Weyland about not believing evolution, by suggesting humans must have had a creator... glaring philosophical hole... who created the tall pale aliens? Evolution perhaps. Peter Weyland would be smart enough to realise the hole in his own logic.
However the rest of it was excellent. Worst part was Walter not realising... almost ruined the film.
