I really like Martha, but I think the writers have done the character a disservice by having her be the second companion in a row to be in love with the Doctor. The pining away for him with her puppy dog eyes (which, I grant, are gorgeous) really gets old. There's been rumors that she's leaving at the end of the series; I hope that's not true. I'd like to see the writers have a chance to fix her. Unless they bring back Sally Sparrow from "Blink." I think she'd be great companion material!
