Nu Who Meta: in and out of character
(Sorry this is late ... I'll post Classic Who tomorrow to separate them a bit)
Since most Doctor Who episodes are written by different writers, sometimes the Doctor's (or companion's) characterization in one episode contradicts their characterization in a surrounding episode. Do you ever see this, and if so, does it bother you? What is the most glaring example of this, and how would you fix it?
