Also TW isn't a children's show. Rose is 19 and starry eyed. The two things can't be compared and Jack/Gwen don't work. The reason Nine and Rose worked was chemistry, she didn't have as much with Ten, and it imploded with smugness. RTD was in love with the Dr and Rose himself. Clearly they knew the fans were sick of the companions falling in love with the Dr, so now we have endless comments about Donna and the Dr not fancying each other.

TW is different, the characters are grown up and love and lust for real, it's an adult programme, the Dr/Rose dynamic really can't work, and may well be the cause of so much of the confusion.
