I'm not sure I like the direction it's going.
I have nothing against the female lead in this - as has been said, Ripley is the protagonist of Alien and it's not an issue at all.
But the setting and purported age(s) of the protagonists doesn't sit right with me.
From the established lore, it's safe to assume the Preds hunt, learn and upgrade their arsenal and/or methods from their findings. So I don't have an issue with them coming to earth at this point in time and learning from a culture renowned for their tracking and hunting abilities.
Where it falls flat for me is the (alleged) age of the protagonists and (and this is conjecture on my behalf) I can't help bu feel they'll play on the psychic/6th sense/Native American trope and tie it in with Billy. I genuinely wouldn't be surprised to see Billy's necklace make an appearance.
And, as much as that may delight some of te fanbase, I don't think it'll make it a commercial success. And the franchise needs a commercial success to ensure "proper" or at least "good" longevity.
