Denzel Washington picks off familiar targets in 'Equalizer 2'

A sequel to a movie based on a TV show is basically the ultimate commentary on Hollywood's infatuation with presold titles, but at least "The Equalizer 2" doesn't harbor many pretentions about its marching orders. Anchored by Denzel Washington's steely presence, it's a spare, brutal vigilante exercise, with an element of righteous revenge mixed into the balance.
