I agree. Human Nature/Family of Blood was overrated in my book. Iceman hit it on the head: too soap opera-y
That's what I liked it for, to be honest. It was the one time when the show really could be. We actually had a human Doctor. Well we didn't. We all knew he was a Time Lord, but he didn't and that's what made his 'love story' really great. It's the only time in the entire run that I have believed the Doctors feelings for another. More than with Rose or Reinette or anyone else. He and Joan in that story just felt so real.
