If anything, if we're going to talk about "Arcturian Poontang", it should be addressed that in the year 2179, people are still f**ked up enough to dominate, probably a smaller community deciding to revolt against corporate interest, to send out marines, who are at that point, basically corporate security to keep the endless flow of cash and exploitation and lack of education going, in an endless expanse of depression. Transgender colonists, or colonists who are forced into acting as transgender, usually under age from the years of 15-18 for the pleasure of marines, is hardly a joke. The entire thing is depressing and f**ked. The fact people in the armed services used to joke about teenagers they f**ked and reducing them to "you f**ked a trap" is pretty sickening actually. Or how many teenagers in Vietnam were trafficked, beaten, etc.
All of this, surprisingly, fits in how terrible the world of Alien is, so good on James Cameron.
