In a lot of fiction books about the Romanovs, the girls or one of them or some of them are depicted as disliking Rasputin, however this betrays the author's and/or history's prejudice towards Rasputin. They probably never knew or heard much of the more sordid side to his character, and probably loved him very much. The only exception may be Olga, as I heard that after Rasputin was murdered she said "I know he did lots of bad things, but why did they have to treat him like this?" but even that statement to my mind doesn't suggest that she disliked him.
