Maybe not as much as Alyssa Milano disliked her in real life, but there was just something about her that didn't make her your favourite. You probably liked her the most in the episode 'Once Upon A Time' because she was so carefree and well, a child. Prue was just always so proud and serious and preachy that it was sometimes a bit too much. You then found out that her and Alyssa didn't get on in real life and whilst it hasn't been confirmed if that was the real reason Shannen had to leave the show, you can guess that most people were on Team Phoebe.
