Not really imo? So far anyway. I’m on like episode 7 and the aliens are like a side character at best, rumors that they destroyed x or y planet, “they blew up my home world” etc but you don’t really feel their might or get the sense that it’s extinction level serious. There’s a lot of telling and not showing if that makes sense. We spend a lot more time on unsc bureaucratic scheming and evil nonprofit lady’s schemes.
I did like the opening scene where they massacre the civilians on madrigal, lots of good "people getting exploded by plasma weapons " stuff, but since that point there hasn’t been a lot of aliens being cool and violent which would be a big draw for me. I hope we spend more time on covenant political dynamics outside of evil nonprofit lady as well
