I sometimes like to dream of a parallel universe where Davies stayed on longer, Tennant did at least one more year, Smith never came on, and Capaldi had come after Tennant. At times I think Capaldi channels Tom Baker a bit too much, since he himself is a fanboy, but I have liked his performance and bringing back an aloof Doctor (again channeling Tom Baker). I was wanting an older actor the whole time the show had come back. I'm hoping they go with another middle aged actor at least for the next choice.
