Sylvester McCoy’s seventh Doctor is without a doubt my favorite of the old show Doctors. I know I’ll get some hate for that, but it’s true. At the same time, the companion he’s often associated with, Ace, kind of gets on my nerves. I do like her, but not as well as her predecessor Mel. Mel, like Sarah Jane, has a love for life and excitement that’s almost contagious, even over a television screen. She also has a degree of usefulness, not to mention one of the most believable personalities aside from the Doctor in the show, which is why she makes the top 5.
