Classics like Alien and Predator have shown people how far our society can go with Sci-fi. Obviously, the acting isn't always the best *cough* AVPR *cough* but I try to look at it from a scientific standpoint. The concept that a human xenomorph is interesting even though it's a large leap from the normal formula that Alien has been following until recently and people still don't like the last two films since they broke the timeline.
