This is my opinion only, but I personally prefer the Aliens franchise to be of a more mature nature, geared towards adults. I mentioned this before, elsewhere, that I consider the Aliens film to be a sort of adult fairy tale, sort of like Pan's Labyrinth. Yes, it is the story of a child, but it is not a story for children. When I was in grade 7, it was precocious of me to read the Aliens comics, and my parents never saw what was in them. I wouldn't let them. I liked that feeling that I was reading something more mature that wasn't patronizing me, or trying to turn it into a junior subject. As an adult, I feel less geeky about my Aliens books on my bookshelf because there is a certain maturity there. They're not children's comics or stories like Avengers or Spider-Man.
Taking these mature subjects, and turning them into something that engages a younger audience will inevitably whitewash much of the horror of this series to make it palatable to younger viewers. This is a trend, that from my perspective as an adult who enjoys the series for its adult nature, does not bode well for the series. The disturbing horror of the series is at its core. When you take it out, what is left?
I have spent 20 years designing toys, and I understand the logic of what is happening. There is an incentive to make the Aliens brand accessible to a younger crowd. There are millions to be made there selling toys, gadgets and all sorts of goodies. I am not privy to your demographic research, but would expect the Alien fan base to be consistently adults, and as a consumer, I would hope it remains so, and perhaps from an ethical perspective, it should remain an adults-only property. If young adults or teens are to access this material, it should be because they are mature enough to want to read adult material, not because they are fed drivel without essence.
