In the aftermath of that HBO documentary about Theranos, a lot of people are thinking about its founder, Elizabeth Holmes.

There's that thing about how she managed to hoodwink investors into pouring millions into her company, then there are questions over her apparently fake deep voice, and the whole Steve Jobs turtleneck thing.

While you ponder all that, Tavi Gevinson of Rookie fame has the best impression of Holmes we've seen so far. It's terrifyingly brilliant.

By the way, there is already a biopic about Holmes and Theranos in the works, with Jennifer Lawrence set to star.

Although if we were casting the film today, we would happily hand the role of playing Holmes to Gevinson. Just saying.
