QuoteI know that Giger envisioned the Alien as a kind of solitary predator
Giger, O'Bannon, Scott...
Actually, O'Bannon envisioned them as having their own culture, a stance Scott agreed with. After the stage we saw in the first movie, it would become something more intelligent, with a society and rituals and what-have-you. Giger worded it best - Not only is the Alien deadly, it's also ignorant. Personally, I think that would've made the Alien better than any hack-and-slash movie monster out there. Something that is actually intelligent, with a definite society but one we can't comprehend. Now it just runs around screaming at people.
