That's precisely it. Covenant made events out of sequences that should've been resolved in seconds.
Prometheus offed its cast pretty quickly. They died in groups and build ups and deaths weren't the primary focus. Snake kills some guys here, zombie thrashes some people there, Engineers smacks these guys, oh and these other guys kamikaze. Done. Mere minutes total.
Covenant?! Covenant!! Covenant really thought we'd enjoy spending time with Rosenthal. Did we really need that entire two minutes, from the neomorph climbing, to her reaching for her gun, to yawn, the screaming in the distance? No attempt to subvert expectations at all. Every shot matters. Ridley just shoots from several different angles and slaps it together later. But every shot matters. It's the rhythm. Imagine Brett's death with us hanging out with Big Chap a couple seconds prior.
Upworth and Ricks? f**k them, let us just discover their bodies. I'd rather we spend time hearing some good dialogue from David or Walter. Or some more engineer shit.
Lindelof had it right. Play the old hits but in new ways and limited quantities.
The whole story sucked though... colony ship? It was wrong right from the start. Colony ship?! Give us scientists, corporate suits, and guys with guns.
