Dustin Hoffman makes his directorial debut in "Quartet." Kerry Brown/2012/Weinstein Company.

This week's new movies include Dustin Hoffman's directorial debut about a home for aging musicians and a documentary about former Cream drummer Ginger Baker. Here's what the Post critics had to say:

*** "Quartet" (PG-13) "Smoothly navigating the perilous line between insufferably twee and heartbreakingly grim, 'Quartet' is a subtle, sure-footed delight -- made all the more enjoyable by the fact that it was directed by a 75-year-old first-timer named Dustin Hoffman. Judging from this debut, the kid’s got a future." -- Ann Hornaday

*** "West of Memphis" (R) "'West of Memphis' makes a lucid, absorbing contribution to an epic saga that [Joe] Berlinger and [Bruce] Sinofsky first wrestled into an 18-year-long narrative that changed two lives and saved one. And it gives that epic an ending that’s happy, sad, inspiring, infuriating, right and terribly wrong, all at the same time." -- Ann Hornaday

*** "Beware of Mr. Baker" (R) "Washington native Jay Bulger’s biographical profile of British drummer Ginger Baker (best known for his work with Cream and Blind Faith) is a fascinating character study of a brilliant and difficult musician, but it also gets at a bigger problem than Baker’s well-documented and long-standing addiction, violent temper, irresponsibility as a husband and father and ineptitude as a businessman. Just how much bad behavior is justified by transcendent art?" -- Michael O'Sullivan
