After three Alien films he's directed under his belt its very appear ant this guy is an overblown hack and never had anything beyond medicore propped up by HR Giger's influence. In Alien, Prometheus, and Covenant its been the same exact movie he's been doing but each one even less interesting than the last.
Astronauts pick up a signal in space, go down to alien planet, find derelict ship, investigate, someone gets infected, monster is born, android turns evil and tries to protect monster, crew dies, ship is damaged or destroyed. Rinse and repeat with the same plot. Even James Cameron and all the others who came after him knew you couldn't just tell the first story over again or else it becomes a dead franchise, and that's exactly where this franchise has gone.
