I checked out the article and I have a very different take on sexuality in the Alien franchise.
* I didn't find David's attraction to Walter to be very disturbing considering what I have seen before in Alien movies.
- The horror in "Alien" is fundamentally based on rape. The facehugger makes that clear. And Ash trying to shove a rolled up magazine down Ripley's throat just adds to that.
"Aliens" and "Alien 3" don't have much creepy sexual imagery.
- But "Alien Resurrection" definitely does.
The licking of Ripley by her huge hybrid baby and Ripley falling into the Xeno womb so to speak, in AR is definitely creepy.
- On top of this, artificial intelligent life forms having heterosexual relationships was already established in "Blade Runner". I realize they were genetic clones but still, they were designed.
If heterosexual replicant sex had already been established, I don't think it's very shocking that androids might be interested in homosexual relationships. Why not?
* As for who created the Xenomorph, I have realized for several months that Ridley is not making another Alien movie. Disney doesn't want that.
- This means the David story is over because I don't think Disney is going to continue that.
The Alien franchise is limited to the movies that we have.
So, all the plans that the Fox studio had for several prequels and what Ridley said during the press coverage for "Covenant", no longer applies.
- Instead, the Canon explanations for the origin of the Xenomorphs, made before & during the release of "Prometheus", are the ones which are valid.
* The Space Jockeys/Engineers created the Xenomorphs as weapons. They are related to the Deacon which we saw in "Prometheus".
There is a Xenomorph egg in the wall sculpture from "Prometheus".
- What did David do? He re-created what the Engineers had already done many years before.
