I love the Catherine Tate Show and was surprised to find her in Dr Who a few weeks ago. I'd never really given the show a chance until recently, and although I don't get to see it very often, I'm rather enjoying it.
My only qualm is that I have difficulty seeing her as someone unrelated to the CT Show. I keep expecting her to come out with an "I ain't bovvered!" or "Who dear me dear gay dear no dear!"
