39. Shannen Doherty
Worst Performances: Mallrats (1995), Burning Palms (2010)
Maybe it's all those reports we've read about Shannen Doherty, the ones that paint her as a behind-the-scenes terror who directors and producers dread working with because she adds unnecessary stress to their lives. According to the rumor mill, she's a real diva. Whatever the case, though, Doherty's performances convey an air of indifference, like she'd rather be anywhere else than on the particular movie or TV show set. As a result, watching Doherty act becomes a chore in and of itself. Call it "negative attitude transference."
