Best Of: The Life & Music of Janis Joplin / Kathryn Hahn

Onstage, Janis Joplin oozed confidence, sexuality and exuberance, but biographer Holly George-Warren describes the singer as a bookworm who worked hard to create her "blues feelin' mama" persona. Her new biography of the '60s counterculture icon is 'Janis.'

Also, film critic Justin Chang reviews the psychological thriller 'The Lighthouse,' starring Willem Dafoe and Robert Pattinson.

Kathryn Hahn stars in the new HBO series 'Mrs. Fletcher' as a divorced mom grappling with her son going away to college. Hahn is known for her roles in 'Transparent,' 'Parks and Recreation,' 'I Love Dick,' and 'Private Life.'
