I recently began watching this show again in re-runs and find it every bit as compelling now as when it originally aired. The writing is gritty and realistic and the story lines often have a universality one doesn't find in other shows, then or now. It maintains a break-neck pace that is always involving. The acting is so consistently excellent that I find it hard to pinpoint a favorite character. It's also fascinating to see the number of actors here, some guesting, some series regulars, who have gone on to greater fame - Alfre Woodard, Dennis Franz, David Caruso, Lawrence Fishburne, Jennifer Tilley, Don Cheadle, Tim Robbins, Mykelti Williamson, Ken Olin, Jane Kaczmarek and many more.
