Nice to see Robin Curtis is doing ok.
I suspect that she isn't (wasn't) any great shakes as an actress, but she was caught between a rock and a hard place. Kirstie Alley had done something nobody could envision at the time: step into the Trek (TOS) crew and become (a well-respected, almost beloved) one of them in the space of just one movie (and drawn wolf whistles from the hetero male geek crowd in the process). Fans wanted Alley back, and the expectations on anybody else trying to step into the Savik role were impossible. RC did her best, and for that we should thank her.
I think the characterization and Nimoys directing hurt her chances a lot. The cut the references to her being half Romulan from wrath of khan (the deleted scene is out there if you never saw it). This explains the conflicted emotions she has in WOK. Since they decided that she was, in fact, full Vulcan, Nimoy decided to make her act full Vulcan. So she was cold, distant and logical in this one. I think Nimoy took away all the fascinating aspects of Saavik, and left Curtis without much to work with.
So the character was super bland, and a new actress on top of it. She never stood a chance.
