So, let's see... Fox screw with Alien 3, which could have been incredible (considering David Fincher's work following Alien 3), they screw with the Ratings of the continuing franchise. And now, they're actually going up against Ridley Scott.
Ridley Scott should fight them, with all he has. And, if he really has too, get James Cameron on board as an Executive Producer or something, to back him up.
Give Scott the money. Give him the 18-certificate.
Let him do something for the fans. Instead of trying to make another trillion dollars after Avatar.
