She was awesome as Dutch on "Killjoys." My initial thought was that she's better than this considering the character is mostly just known for wearing a metal bikini, but after my initial prejudices, I'm sure the filmmakers have more in mind and I hope it's successful for her sake.
Too bad we never got to see the Robert Rodriguez/Rose McGowan film they had wanted to make - that could have been fun. Another Rose that I think could have been a good choice is Rose Leslie - she was almost playing Red Sonja already on Game of Thrones - just with more clothes.
