She never was that hot. Courteney Cocks, on the other hand...
I thought she was visually appealing but the character was so fucking annoying I just wanted to beat her with a hammer.
Cox, I don't know, I thought she was really hot when the show began, then I stopped watching it, years later I saw the show again, and didn't like her.
Jennifer Aniston always blew those two out of the water though. She was pretty much the only reason to watch the show.
