BBC America is running a Doctor Who Marathon this weekend. If you’re a Doctor Who fan or if you’re curious about what all the fuss is about, I’d urge you to set your DVR and get caught up on these recent episodes. I like Matt Smith, the 11th Doctor. I like his companion, the fetching Amy Pond (played by Karen Gillan) even more. Redhead fans, take note! At 9:00 P. M. EDT, BBC America plans to broadcast a new episode of Doctor Who. You know I’ll be watching.
