Depending on your age, you probably have different ideas about what “The Equalizer” is. If you’re, uh, a person of a certain age, you may remember the ‘80s TV drama about a retired agent that takes it upon himself to use his skills to help innocent people in bad situations. If you’re a bit younger, you may think of Denzel Washington’s two ‘Equalizer’ films where he violently disposed of bad guys and looked badass doing it. But if you don’t even remember that, perhaps you’re going to be excited to watch CBS’ new reboot of “The Equalizer,” with Queen Latifah doing all the ass-kicking.
