Had you told me at the beginning of David Tennant's third season as the Doctor that his companion for that season, Donna Noble, would become my second favorite companion of all time, I would have laughed in your face. When the season started, Noble grated my nerves. Portrayed by Catherine Tate, who was known primarily for her comedy work, the character was annoying and a bit too pushy for my tastes. As I continued to watch the season, however, I saw how the character of Donna Noble had many more layers to her than the pushy, cranky surface revealed.
Eventually I began to realize that Donna was a deeply sad person who thought that she was the least important person in the universe. Fans of the series know that she became much more than that, but eventually became an even more tragic character in the end. She was the first companion in the new series to make the Doctor see things from a compassionate angle. In short, she gave the man with two hearts, an actual heart.
If any companions are brought back again, I vote that Donna be the first one called back! Were it not for Elisabeth Sladen's brilliant work as Sarah Jane, Donna would be at the top of my list.
What did you think of this list?
