There's literally no need for the upgrade in this film, though.
Could've just as easily been a Bad Blood which would have a good 90-odd percent of the doubters on-board from the get go.
The fact that the USP is that there exists a clan/branch/type of Pred who is essentially GM, is just a joke.
Shurikens don't sit right with me either. They cement a link to the AvP realm which will dilute the franchise too much, imo. Appreciate AvP has it's fans, but it shouldn't be canon, IMO, sorry.
