To be honest, the worst actress in my opinion would have to be Kristen Stewart from Twilight. I did not enjoy Twilight. I just watched the first one because I could not stand her. She has the same facial expressions when She's mad, sad, happy, angry, depressed, sleeping. Like, she's a bad actress. Actors, I can't think of any right now, but Kristen Stewart is the worst actress, in my opinion. What's your guys' opinion? who's the worst actor slash actress.
