Even before the extraordinary set she did regarding her cancer diagnosis, Tig Notaro was one of the smartest, funniest, most inventive stand-up comics around. (Google the bit she did on Conan O'Brien's show that involves her scooting a stool around. Go ahead, we'll wait.) But after that Largo gig found its way on to the Internet, she suddenly found herself catapulted into the spotlight — proving that tragedy plus time does indeed equal comedy, provided you have the chops to turn bad luck into an insightful, eye-opening half hour of confessional joke-telling. Kristina Goolsby and Ashley York's doc looks at what happened after Notoro opened up onstage, from dealing with the disease to the sudden onrush of attention.
