Her performance made her a star and minted an image.
Dockery plays Letty Raines, a drinking, drugging ex-con doing a terrible job of rehabbing her life.

The pilot is a twisty setup.
Its a suspenseful scene that recalls the voyeurism and conundrums of David LynchsBlue Velvet.
Should Letty intervene and save the wife?

Dont draw too many conclusions from my summary, or even the first three episodes.
The second models what could be called an assassination-of-the-week plot.
It also pushes the queasiness of Lettys predicament and its metaphor for abusive marriage to the max.
It also readjusts the Letty-Javier relationship and upends your expectation for what the show might be each week.
Itll need zestier storytelling to keep me tuning in.
Dockery is appealing, but not entirely convincing at the grungy, tortured-soul stuff.
ET in a two-episode event, but you might watch the first episode in the YouTube video below.
