That the Character of Shaw is in it, that's OK (as opposed to chopping and changing characters left right and center so there's no continuity between franchise films). But I expect Noomi to really bring more to the role this time around - by default, and also additionally due to her being hardened by the events of Prometheus. We've seen more emotional responses and excitement from REAL scientists during the Pluto/Philae missions than we have from Prometheus' scientific crew.
For me, Shaw's off-screen assumed pushiness/ambition to get to where she was - onboard the Prometheus - didn't seem to match with the often times wallflower persona. Even if she was playing the straight man cool/clinical scientist a la Dana Scully with a crisis of faith vs science twist, Gillian Anderson "gave" more presence on-screen in her debut scenes . And that was for a TV show, not the big screen.
Anyway, I wonder what her role will be. I really hope its written well this time.
