only the first one is "good" the second is fairly pointless and it sounds like this prequel is even more pointless, just a random side story DLC that adds nothing to the mythology of the aliens. watch once at home if you like alien movies and never think about it ever again.
Which is fine, clearly Krasinski isn't interested at all in building out a world like Zack Snyder (lol) or the John Wick guy, and its probably better since a movie trying to explain how the aliens work, why they invaded, where they came from, and who runs them (if anyone) would be something that likely doesn't work and not something audiences would care enough about. Its what most of us here would want but its 10x harder to pull off.
Alien Romulus sadly feels similar too, just sorta retelling the same egg->facehugger->xenomorph->everyone dead story instead of expanding on the lore, which Prometheus/Covenant tried to do but also failed miserably at doing it.
