Well, there are human heroes, altruistic ones too, but the focus is really on the false flag scheming company, ala WY. It's funny, because some criticised Avatar as saying that the aliens needed humans [specifically Jake] to save them, rather than being self-sufficient. I'm sure the same criticism was levelled at Avatar's Earth-bound parallels; the white male saves the poor indigenous peoples shtick. But either way, the focus wasn't entirely on characterisation, but on, effects aside, simple storytelling. It was in some respects a shot in the foot, because simple storytelling doesn't work for more serious-minded sci-fi fans, but the kids of today will grow up to love it, y'know, as they did with Star Wars, which was lambasted by "serious critics" for bringing spectacle and simplistic storytelling back to the screen, [of course, Star Wars was helped by being, really, one of the first of its kind. Avatar, fun as it is, is absolutely contrived in comparison].
