Blood work

Skepticism takes a holiday in "The Inventor: Out for Blood in Silicon Valley," Alex Gibney's jaw-dropping documentary about how Theranos founder and CEO Elizabeth Holmes pulled the wool over the eyes of some of the country's most powerful men with wildly exaggerated claims that she had come up with a revolutionary medical device. The con job is all the more startling after watching her "bond" with employees during history's most awkward rendition of "You Can't Touch This."

Cut-and-dried case

Prosecutor Marcia Clark freshens up her image with "The Fix," a new drama not so loosely based on the real-life aftermath of her failed attempt to convict O.J. Simpson. Robin Tunney plays a supersmart, super-depressed attorney who gets a second chance at going after a movie star who she believes stabbed two people to death. The proof that Clark served as a series consultant is indisputable.

Family memories

Elan and Jonathan Bogarin turn their grief over losing their pack-rat grandmother into "306 Hollywood," a misty-eyed but poorly constructed documentary that seems more fit for a visitation than a spot in the usually stellar "P.O.V." series. The dreamy re-enactments, including a dance sequence on Grandma's front lawn, seem like excerpts from a student-film project.
