I'm not usually one to fall for romantic themes, but I am glad Charmed added the final season. I liked the story lines that were added for the unwed sisters. The addition of Billie might be a bit of a stretch for some people but I even enjoyed her contribution to the last season. I love women that kick ass!
All in all, I'm glad they ended the series the way they did. The seventh season's ending was okay, but I never did care for happy endings with the characters walking away into the sunset.
My favorite part of the last season was
the destruction of the manor and the death of 2 of the sisters
I thought the special effects were terrific. I would have been happy if had ended right there but I don't think die hard fans would have been pleased by that.
