I don't think anyone had any doubts about authenticity to the franchise. To be authentic just means "facehugger- check, ova morph-check, chestburster-check, xenomorph- check" and its AVP all over again just with less of anything new. I think the only way we could at least be acknowledging is "new and improved- checked" which speaks a whole lot more than ...."xenomorphs all over again routinely"
