Don't expect much in the way of personal revelation or public misbehavior. Apart from sucking on a bottle of Southern Comfort, this Janis is quite composed and sedate between songs. She tells charming stories about housecleaning, her family, her favorite 45s. Johnson's script has been carefully policed by the Joplin estate, which consists of Janis's siblings-thus, it's long on stories about her siblings and short on just about everything else. If an alien landed in the theater, seeking knowledge of Janis Joplin, its report to the mother ship would describe a mild, genial hippie redneck whose onstage routine included the occasional nip of hooch-basically Ron White in combat boots and batik, with a song in his heart...Davies's Janis, it must be said, is nothing short of extraordinary in the pipes department: She shreds her larynx like a woman possessed and still has more to give. It's a close but not Xeroxed impression, and in the narrow interstices between impersonation and performance, she injects real feeling and nuance. This is especially astonishing given the deadwood she must deliver. But just when you can't take another anemic anecdote or whitewashed Wiki stub, she lets loose her 'Cry Baby,' her 'Me and Bobby McGee,' and all is forgiven.
