Just a quick thought. Why didn't the Doctor give Rose the choice of returning to her own Universe? She may not really have wanted to spend the rest of her life in a parallel universe (she was trapped there against her will the first time). She would likely have friends and other relatives in her own reality. Mickey's allowed to come back, but the Doctor pushes Rose out to babysit his other self without giving her the option of coming home.
Isn't that a bit cruel?
These two things really bugged me too. Donna deserved better. I know she wasn't planning to return next year, but sheesh.
What he did to Rose just sucked.
I wonder if the reason the Doctor didn't give Rose an option was that she was already proclaimed dead in our universe. As far as the relatives and other people know, seeing Rose again for the first time in years after thinking she was dead might be a real shock to the system.
