Well, um, the actors say - they just plain say it - that it wasn't that they had chemistry and it leaked over to the Doctor and Romana, it's that the Doctor and Romana had chemistry and it leaked over to them. It was the weirdest interview I've ever read. Eventually, you have to grant to interpretation - you might not have viewed them as romantic, but a lot of people did. So is that canon or not? And speaking of Jo, who's to say the Doctor at the end of "The Green Death" was any less broken up than the Doctor at the end of "Doomsday"? There are just bound to be different views there, not the least because, obviously, "romantic love" doesn't mean the same to different people.

RTD had every right to produce his show as he sees fit and I'm not saying otherwise, but I am saying that he has no right to expect the fans to agree with what he's doing. There just... isn't an argument of "the producer says X so X is 100% true" when it comes to characters' relationships. That's what fandom is all about. And that's the "love of the Doctor's life" issue too - it is the same as saying he wasn't in love with people before, and if someone believes he did, they're going to get annoyed.
