David Tenannt has quit as Doctor Who. He was my first Doctor and will forever be tied in my mind to the early stages of the epic Ms Bookish/Scottish Guy (now known as Other Half) long-distance relationship. I watched New Earth and Tooth and Claw (Tennant's first proper episodes) during one of my visits and timed my next visit so it coincided with the breath-taking season finale. Aww. Back then I didn't have a big Doctor Who problem, of course.
Anyway. According to Other Half (formerly known as Scottish Guy), the smart money is on Paterson Joseph to replace David Tennant, although other contenders apparently include James Nesbitt (please, no, no) and Robert Carlyle (he'd be another local boy and, well, he likes my knitting). Any preferences?
