Denzel Washington is Clint Eastwood with a nailgun, cleansing the high plains of Boston in “The Equalizer” (2014). You will either love or hate its bloody, vigilante-style violence. I loved it, particularly as viewed through an earlier Washington character from one of my all-time favorites, “Man on Fire.” In that 2004 movie, Denzel’s Creasy is a lost soul atoning for past sins. Here, his activities, while achieving the same goal through the same methods, are that of an avenging angel. Are those characters that much different, or is it simply our perception? Either way, I look forward to the sequel.
