I don't follow the Dr. Who fandom (even though I love the show), so I wasn't aware a lot of people didn't like this. I heart it, even with Donna's totally heartbreaking end.
Yeah, I never had a problem - and often it's best to stay away from fandom! *g* (Not that I can't understand people's objections, but I am able to ignore them!)

She's still my fave companion. Donna Noble rocks!
There's only one Donna!

And Wilf!!!! I heart him to infinity and beyond. Heh.
Wilf is everything that is good. (More or less. And you know that the actor was in the Doctor Who movie waaaaaay back in the day, right?)
