The Equalizer, starring Denzel Washington and Chloë Grace Moretz, is a loose adaptation of the 1980's TV series of the same name. McCall, played by Denzel, is a former black ops commando who helps others by seeking vengeance for crimes committed against them.
His first mission, is to try help Teri, played by Chloë, a young prostitute being exploited by Russian Gangsters. She gets badly beaten up and he takes matters in to his own hands to help her. He quickly learns that the men at the centre of the gang have their fingers in many pies and are colluding with the police. In order to take the organisation down he must target every aspect of their business.
It's full of action, suspense and violence, as you would expect with gangsters involved. Denzel is the perfect action hero for this movie, retaining a calm composure throughout, even when faced against four angry Russians armed with machine guns. His character is quirky at times, particularly with time keeping. He sets time limits for himself for most aspects of his life, including taking down gangsters (which is less than 30 seconds).
It's not unlike the movie 'Taken' but with Denzel as more of a vigilante or 'superhero', well minus any super powers. The only downside to the movie is that it's quite slow at some stages, but the excellent action throughout makes up for it.
