I dislike Jennifer Aniston. I feel kinda guilty about this, because it really isn't so much her own fault that I hate her, as much as it is the media's. She wouldn't bother me at all if it weren't for the fact that she is shoved in our faces at every turn, and that The Powers That Be have decided that she is a goddess on earth who is so talented and perfect and blindingly beautiful that any self respecting magazine needs to have her on the cover at least 1000000 times a year. Yeah, I know it's not (completely) her fault, but still. Her overexposure is completely undeserved given the amount of her "talent", and it bugs.
And yeah, Ben Affleck. For the same reasons.
EDIT: Maybe I should add Jennifer Lopez to my overexposed Hall of Shame, but the truth is, with J-Lo, everybody already hates her. Both the general public and the entertainment industry knows that she's overexposed/undertalented, and jump at any oportunity to dump on her. Not even other actors can stand her, and that's what seperates her from Aniston/Affleck.
