Noomi was great in 'The Girl with the Dragon Tattoo', in terms of 'Prometheus', she was just given the wrong material.
I know people will point the finger at Lindeloff but really, it's the Director that needs to pick up on weaknesses within all parts of the Production and address them. Scott really should have pulled his finger out on that one.
He could have had a great character on screen, if the actor was given the right material (or even the wrong material) and directed well.
As it stands, Shaw comes across as vapid and ineffective. Noomi could have really brought a great character to life given the right conditions. This movie wasn't it.
