"Lizzy Caplan has always been chronically underemployed, and I think in part that’s because there aren’t many roles that answer her combination of engaged enthusiasm and sexy intelligence. This is the perfect role for her. At no point does the show pigeonhole her into either cute or sexy or smart or funny. She has the freedom to be all at the same time, and let loose of those strictures that so often constrain women’s performances, she’s a remarkably fleshed-out character, recognizably modern, and in fact, so modern that she is a fish out of water in 1956. The way that she’s filmed and dressed compared to her backgrounds just emphasizes that: She stands out effortlessly, with her dark hair and expressive eyes and animated smile, while Masters, in his bland white coat and hairstyle, more often than not blends right in."
The AV Club on Masters of Sex. A much better show than you imagine. And how Lizzy Caplan landed the most dynamic female lead on television is a mystery but I’m so glad she did.
