I was first introduced to Claudia Black as the mischievious Vala Mal Doran on Stargate. From her very first appearance, it was clear that this interesting character had a spark with Daniel Jackson. Two years later, she has been made a regular on a show that is currently in its 10th season.
Since the departure of Richard Dean Anderson, something has been lacking in the show. With the addition of Vala to the cast, it has regained a fun, playful group dynamic that was sorely missing in season 9.
Since discovering Claudia Black on SG1, I have started also to watch Farscape. She is an amazing, beautiful and talented actress capable of carrying a show on her own. In fact, once Stargate runs its course, she should get her own show!
