They screwed up their intentions with Shaw in Prometheus. They actually left a crucial bit of her character on the cutting room floor... Along with most of the movie's motivations and characterizations, but I digress.
In one of the promo materials where Shaw is trying to talk to Weyland, she better describes her beliefs vs what she knows as a scientist, and it comes off much much better than the clipped version we get in Prometheus which only further added to what makes the film seem scientifically... retarded.
