“The Equalizer 2” is another summer sequel, this time with Denzel Washington as a bad ass, avenging innocent victims. He helps out a kid being recruited by a neighborhood gang, the murder of a friend, a holocaust survivor, and others. One lesson that his enemies don’t figure out until it is too late is don’t mess with Robert McCall, Washington’s character. The movie starts off with a bang, literally, and keeps going from there. Denzel is excellent, as always, and we learn a little bit more why he became the loner he has become. Not quite as dark as the original, it is still violent, but compelling. A good action film.
