Let's not forget the utter silliness of that girl running around and doing action hero stuff just five minutes after undergoing major abdominal surgery. Oh sure, the script called for her to grab her tummy and wince now and then, But she was no more convincing doing that than any of the other things she did. Ripley, she ain't.

Charlize Theron was totally wasted in this movie as the Burke character from Aliens. At least she can put in her resumé that she was once killed by a spaceship falling on her. Not many people can say that.
