OK... it was better with Jerry Orbach as Detective Briscoe, but whatever. It's a fabulous show with good plots and climaxes, but lots of blood with the bodies, lots of guns, and sometimes the cops get rough with a suspect. And also, there is an underlying sexual act. (Nothing explicit, though.) The premise is good; people do bad things and they get punished. (Not always, though.)
Good for older kids; younger kids may not understand the plot or the blood for effect.
