You can focus on AI, but there still could be some Aliens in the next movie, I dont get why most of the peple see this as a main problem. . David experimentation (perhaps on Daniels or other colonists) will produce once again a new kind of various creatures, of course there would be some Aliens in it, why these two little facehugger embryos would be even there, if we dont have any creature in the next film, huh? Jesus, use your brains guys! I love androids from Alien series since the first bloody encounter with Ash, you know. The Ash decapitated head, white blood and all this mess stuff. But the Bishop is my most favourite character at all, especially because he was super good "person". . and I love him as an actor, but since these two Androids. . I never actually thinking about how they are important for the whole Alien universe. And now I found that, that they are very important. Just think about it, we know almost nothing about human civilization in these movies, we know that humans can colonize the other planets or moons, produce some huge spaceships and vehicles, than we have our so called evil company the Weyland-Yutani, some colonial marines and thats all. . another, last and most interesting fact is, that humans can create the artifical life, and I think that, this is very important aspect of these movies, its like a cherry on top of the cake. Of course there are mainly Aliens we all like the most, but in the terms of the humans, the Androids are specials. So, Im glad that we can have some focus on David, not only because he is a villain. . but because he is the Android, and not just a regular android. Oh, and by the way. . we have AI in almost every Alien film, if not the androids, than there was also computers like "father" in Alien Ressurection, or mother from first movie. So AI is fairly common in Alien series, just dont forget that David is the main plot device for the whole experiment around the black goo etc. There is no human that can do the exact same stuff like David did in Alien Covenant, it will kill all humans that came in contact with it. Like it or not, we need the David, at least for this third part. And I dont have anything against it.
