A few months ago I was chatting with my father about how I was about to start watching the Peter Davidson episodes along with you guys, and well, he told me his opinion of him. To set things up a bit, I grew up hearing stories from both my mother and step-mother of my Dad's Doctor Who addiction, so he's been a fan for quite sometime. His opinion of Peter Davidson was that he was... well let's put it nicely, a "pretty boy". Not the word he used but I refuse to use that word outside of xbox live!
Anyways, from this anecdotal story I'd say people of the time who were use to Baker probably saw it as a move to pretty up the cast to get more viewers. Pretty much what they do now from the get go on most TV.
I also find it hilarious that you guys said there was no news when Torchwood had it's season finale. Kind shows what whimper of a story it had. Just watch the finale and let's just say, meh. It really could have been great, but it just felt like a mish mash of so many things.
Are you guys going to review Torchwood?
Keep awesome, guys!
