I dislike Ashton Kutcher (spelling?) because Punk'd seemed so mean at times. I never got what was so great about it.
I dislike Laura Bennett from Project Runway, Season 3. It's unfair, though, because part of the dislike stems from her crazy worshippers. People act like she's the second coming of Christ sometimes. It gets like Angelina Jolie rabid fandom if you say something kind of negative about her.
