DIRECTED BY JAMES CAMERON
Why's it so good? Cameron's genius here lies in manipulating the tension, beautifully structuring the switches from build-up, to carnage, to unbearable waiting, to action. The Colonial Marines who accompany an understandably reluctant Ellen Ripley are each fleshed out as individuals, and the plot brilliantly conceived to showcase every character and then kill most of them off horribly. Why does it beat the Godfather Part II? Because that doesn't have a single acid-veined xenomorph in it, that's why!
