I still believe in Ridley Scott, even if I'm the only person on god's green earth that liked Prometheus. So Charlize Theron is not an ambi-turner; so what?
Why does everyone thing that Ridley Scott is the genius behind Alien? The real genius behind that movie was Dan O'Bannon. Nothing that Ridley or that hack Cameron did is canon in my not so humble opinion. And no the "alien" is not a race, it is a weapon. Please get that straight.
