"It's just sounds too normal"
I agree. That's kind of what I was going for. It's honestly what I figured Scott would do if he chose to focus on David's obsession with Shaw, or just a basic (bare bones) continuation of Prometheus. Perhaps the unwanted inclusion of the xenomorphs in Covenant, may have had a more significant effect on the finished film than I first thought. I do hope though that we one day get at least a novel or something that more thoroughly details the events leading from Prometheus to covenant. It might make for some good close-quarters tension, and any further information David learned about the engineers would be interesting. Regardless of what happens to the franchise after the 3rd film, I hope Ridley really nails it home with the last one. I may not be a fan of the prequels, but if we must have one more, I'd rather it be a solid film, and see Ridley go out strong.
