Is there an actor/actress that you dislike so much, that no matter what they're in, you won't watch it?

Who is it and why? For me it’s Tom Cruise…he irritates the crap out of me. He seems so arrogant and egotistical. Another one is Bonnie Franklin…from an old TV show show way back. I don’t even know why, she just annoyed me so much I had to turn off the TV. With Cruise, I know more about his personal life and think he’s an idiot, so won’t see anything he’s in. With Bonnie Franklin, I just hated her on that show (what was it?). No other reason.
How about you?
