Great actor and seemingly wonderful person. But she represents all of the bias you find in artistic evaluation. You can look at any clip of The Iron Lady, and you will never, ever believe it's a real person you're looking at. But she's Meryl Streep, so, ipso facto, it's great. Viola Davis's performance of Abilene was miles better. And I'll go even further: Kristen Stewart's performance in Breaking Dawn was miles better.
