Davidis awesome. And yet I really liked Shaw! I think Noomi Rapace is a great actress and gave Shaw who gave Shaw many facets. Weakness and self doubt and naivite, and yet her passion made her brace and relentless. When she cut out that embryo and patched herself up, she was becoming a real bad ass until the end of her movie.
A woman who can't bear children who is searching for an answer to why humans are the way they are. Maybe that was sub consiously another reason, why she was looking for the engineers. Not to prolong her own life like others. But to find a way to create life! To find out what happens after death, or lets say get a grasp of the universe, and find out why humans were created, and ow it all connects, is maybe just one aspect of her.
And then what she is getting, is a traumatic abortion, and the creation of a life, that means DEATH to everything else. Her search for wisdom gives birth to a snake, to put it in biblical terms. How does a character come back from that? And how does she get back at this universe who treats her so badly? Her anger which makes her going even further, is really one of strongpoints of Prometheus final scenes. As well as her relationship to David, who she still accepts more or less as being who acted in accord with its own concepts, rather than just hating him for what he has done.
Her search for Paradise is a plot point I would deeply miss in the next movie, if they were to ignore it. But I like the fact that nothing is revealed in the details as of yet. They can build up the mystery around her in the following movies. But I defintely want to see her again.
