"Our imaginations are wild, if we exercise them. I chose to just, as this character, believe in everything. And when I was told that something wasn’t true, I doubled down."

Said Amanda Seyfried, quoted in "The Women of ‘The Dropout’ Want to Humanize Elizabeth Holmes/In a group interview, Elizabeth Meriwether, Amanda Seyfried and Rebecca Jarvis discuss the new Hulu series about the fall of Theranos and their efforts to reveal the woman beneath the turtleneck" (NYT)(Seyfried plays the part of Elizabeth Holmes). 

The NYT interviewer, Alexis Soloski, does a nice job of highlighting the problems with the show without overtly confronting the interviewees about the weakness of their project:

Theranos claimed that it could run more than 200 tests from a finger prick’s worth of blood, which would have made Holmes the kind of visionary that young women — women like Seyfried — could have looked up to. But the technology never existed....

Because Holmes has consistently denied any allegations of fraud, it is nearly impossible... to know Holmes’s mind and motives. This makes “The Dropout” a series built around a cipher....

Who is Elizabeth Holmes?

ELIZABETH MERIWETHER Oh boy.

AMANDA SEYFRIED I think we’re still trying to figure that out....

MERIWETHER Even writing the scenes of the things that I knew had happened, it was a challenge figuring out what was going on in her head. That ultimately makes the series more interesting, because there are just things about her that don’t make sense....

ADDED: Rereading that, I see that the women who made the show are kind of like Elizabeth Holmes. They promote their enterprise, but they don't have any idea of what they're doing. Holmes didn't have the technology for testing blood like that or any hope of finding it, and these women don't have a basis for knowing the interior of the woman they purport to delve into or any idea of how to get there. I mean, they could have decided Holmes was a big fraud from Day 1. That would have made sense, but that's not the story they wanted to tell.
