I didn't like her wooden acting and boring character in SG1. She wasn't as bad as the scientist guy, he made me rage for various reasons.
I watched some episodes of Sanctuary, somehow I liked her better there but I didn't like that show either.
So uhh... I'm voting thumbs down based on what I've seen of her as an actress. Mostly because I got tired of her saying "With all due respect, sir...". Not that it's her fault but i'm feeling evil today. I don't really care about her looks. She's pretty, specially with dark hair.
