The best movie ever made about slavery is also the best movie of the year. No prettified classroom study for director Steve McQueen, a visual artist and visceral provocateur of the first rank. He rubs our noses in the horrific true story of Solomon Northup (Chiwetel Ejiofor), a free black man living in New York in 1841 until he becomes enslaved in the Deep South. Ejiofor, his eyes pools of torment, is an acting giant. This is one for the time capsule.
