Dave Tennant's Dr Who episodes have arrived in the states, and I more than agree with what Rachael or Karen said about him filling the role. I've almost forgotten the actor who came before him. In the pictures, he looks like a skinny, nerdy guy in a suit, but his performance is really strong.
I like watching Dr Who also because it gives me an idea what the Brits are thinking. Its a change watching a show in which the aliens always strike London instead of New York.
My only real complaint is that sometimes the show's forays into current politics are a little awkward. The "cat hospital" episode seemed to be making a statement against stem cell research, but over-simplifyinging the argument.
The pure entertainment episodes come off a little better, I think.
